I was doing math with my 13-year-old daughter Hannah and had another leadership epiphany. If you are thinking this sounds like my last blog, you are correct. Yes, I am learning leadership lessons from math. I started college thinking I was going to be an engineer, so maybe my mathematical inclinations are being stirred. Thus, be prepared for a modified math tool that will help you help others learn new skills.
Let me first set the stage for the focus of this tool. Leaders help people learn new skills. Sometimes, the challenge is getting to the core skills that will maximize growth. This is where the mathematical insight begins. There is a mathematical process called prime factorization that illustrates the process of getting to the core skills of a given task.
Prime factorization is a mathematical process of determining which prime numbers multiplied together make the original number. Prime numbers are numbers that can only be divided by one and the number itself. Here is a list of common prime numbers: 1, 2, 3, 5, and 7. A factor tree is a way to find the prime numbers that when multiplied together make the original number. Here is an example of a factor tree using the number thirty-six.
In this example the prime numbers are 2, 3, 2, and 3. When these numbers are multiplied together, the product is thirty-six. This same process can be applied to a task in order to determine the core skills. I will use the example of riding a bike down the block and back to create a task tree.
A task tree starts with the central task. In this case, the task is riding down the block and back. The task is then broken down into specific skills as this illustration shows. In this task tree, we see the core skills are start, accelerate, break, balance, and steer. These are building blocks to complete the task, and each skill is needed to accomplish this specific task.
In this example, the core skills are asking questions, listening, lead warm-ups, setting expectations, capturing ideas, aligning agreement, navigating conflicting perspectives, identifying the purpose, and keeping people on topic.
These are two examples of creating a task tree in order to identify the core skills. As you practice identifying core skills, do not get stuck by trying to get it perfect. There is no flawless task tree. The important concept to consider is breaking down the task into clear core skills so you can better understand where to focus development.
Math comes through again. If you or someone you work with is struggling with a particular task, create a task tree to clearly identify the core skills. Then, identify the key core skills that need training. This will provide the opportunity for focused development.


Understanding your interest rate and how the interest is calculated is important if you want to tell a good deal from a bad one. One of the problems people often encounter involves the difficult calculations needed to work out compound interest rates and how does it affect your overall mortgage deal?
Compound vs. simple interest
Compound interest (sometimes referred to as ‘rolled up’ interest) is by far the most common form of interest on UK loans and mortgages. It is a fair system of interest calculation though more complicated mathematically.
Simple interest means the interest is calculated on the start value of the loan (called ‘the principle’) and never changes throughout the term of the loan.
Compound interest is recalculated as the loan is paid back, making it a more accurate reflection on the loan in current terms.
An example of simple interest
£1,000 loaned over 5 years with simple interest at 10% will incur £100 in interest each year, irrespective of how much has been paid off. By the end of the term, £1,500 will have been paid back in total – the principle £1,000 plus five years of £100 interest per year.
Simple interest is easy to calculate but over a long term will quickly result in far more interest being paid than a comparable compound rate.
Compound interest is recalculated as the loan goes along.
A simple example of compound interest
Again, take £1,000 loaned over five years, with 10% interest and £260 in payments being made each year (unlike the simple interest example, the payments are needed to illustrate how the compound interest works). The following table shows that balance at the end of each year and the interest that will be added:
After the final (slightly larger) payment is made to clear the remaining debt, the total that has been paid back is £1,323.18 – almost £200 less than the simple interest alternative. This is because as you pay back the capital of the loan you are making the balance smaller. As the interest is calculated on the balance and not the principle, each year less interest is added.
Compound interest and your mortgage
The small £1,000 loan version over five years given in our example showed a saving of almost £200 – close to 20% of the principle. The longer a loan goes on, the better an alternative compound interest is to simple interest; similarly, the larger the loan, the better compound interest is for the borrower.
And what’s the largest and longest loan you are ever likely to have? Your mortgage.
Crunching numbers – the true compound interest calculation
The simple example given above had the interest calculated annually, but in reality your mortgage interest is calculated monthly meaning every time you make a payment you lower the balance and thus the interest on the next month’s payment.
With compound interest and a repayment mortgage, the longer you get into the mortgage term, the more of the capital each month’s payment chips away. This has the joyous effect of helping you see the light at the end of the tunnel as you get closer to the end.
The maths behind compound interest can be overwhelming, but we live in a world of calculators and computers, so thankfully we don’t have to use a pen and paper ourselves. There are many online compound interest calculators out there to help you work out the exact numbers (if you want to!).
Overpayments – getting a bigger chisel to chip away!
If your mortgage deal allows for penalty-free overpayments then it’s great to take advantage of this if you get in some extra cash, such as from a bonus. Making an overpayment doesn’t just take that amount off your balance, it also lowers the amount of interest your mortgage will accrue for the rest of time!
Taking a chunk off your mortgage balance of a couple of thousand pounds every now and then can strip years off your mortgage term in the long run and is well worth doing if you can afford to.
Buy-to-let interest only mortgages and interest
A BTL mortgage is likely to be an interest only loan, meaning each month you only pay back the interest and never touch the capital. At the end of the term, the principle of the loan still needs to be paid back (but don’t worry, there’re plenty of ways to easily do that!).
Interest only mortgages have very low monthly costs, because you are not trying to chip away at the capital and only keep the interest from building. They do follow the rules of compound interest, however, and if you ever make a payment with the intention of lowering the capital balance, then the interest will drop accordingly.
When compound interest is bad for you
While slightly out of the scope of our specialisation here at The Mortgage Hut, an article on compound interest would be incomplete without a quick mention of loans running away with you. With your mortgage, you make regular repayments that keeps the interest paid and lowers the capital over time, but what if you have a loan where your monthly repayment doesn’t even cover the interest?
This can happen with some loans and means that the capital increases each month rather than decreasing. Then the interest in the following month is larger, the payment is not enough again and the capital increases further – this can spiral out of control very quickly with interest piling on interest relentlessly.
Our advice – never take out a loan if you can’t afford the repayments!

For enthusiasts of lottery and betting games, the quest for unlocking the secrets to consistent wins often leads to the realm of Toto analysis methods. In this comprehensive guide, we’ll delve into the strategies, techniques, and approaches that make up the Toto analysis method, offering players insights into the art and science of maximizing their chances in this game of chance.
1. Understanding Toto: The Basics of the Game
Before diving into the analysis methods, it’s crucial to grasp the fundamentals of Toto. Toto, a popular lottery game, involves selecting a set of numbers with the hopes of matching them to the drawn numbers to secure a jackpot or other prizes. The simplicity of the game makes it accessible, while the unpredictability keeps players intrigued.
2. Statistical Analysis: Leveraging Numbers for Informed Choices
One cornerstone of Toto analysis involves statistical methods 토토분석방법. Players can explore the frequency of drawn numbers, patterns, and historical data to identify trends. Statistical analysis enables informed choices, helping players make selections based on the likelihood of certain numbers appearing in a draw.
3. Pattern Recognition: Unveiling Trends and Sequences
Patterns often emerge in the randomness of lottery draws, and Toto is no exception. Analysis methods focus on recognizing patterns, such as consecutive numbers, even-odd combinations, or specific number groupings. By understanding these trends, players can make more strategic choices in their number selections.
4. Wheeling Systems: Optimizing Number Combinations
Wheeling systems are a popular component of Toto analysis methods. These systems involve strategically arranging selected numbers to create multiple combinations. While it doesn’t guarantee a jackpot, wheeling systems enhance the chances of winning smaller prizes by covering various possible outcomes.
5. Hot and Cold Numbers: Riding Winning Streaks and Identifying Lulls
Hot and cold numbers refer to the frequency of certain numbers appearing in draws. Analysis methods often involve tracking these trends, riding the momentum of hot numbers while also recognizing potential shifts. Players can use this information to make dynamic choices in their number selections.
6. Frequency Analysis: Identifying Overdue Numbers
Certain numbers may not have appeared in recent draws, creating an opportunity for players employing Toto analysis methods. Frequency analysis involves identifying overdue numbers that are statistically more likely to appear in upcoming draws. This strategic approach aims to capitalize on the natural ebb and flow of number occurrences.
7. Combination Strategies: Balancing Risk and Reward
Effective Toto analysis methods also consider combination strategies. By striking a balance between high and low numbers, even and odd selections, and spread across the number pool, players can create well-rounded sets that enhance their chances of hitting winning combinations.
8. Randomness and Chaos Theory: Embracing the Unpredictable
While analysis methods provide valuable insights, Toto remains a game of chance governed by randomness. Embracing chaos theory, players can appreciate the unpredictable nature of lottery draws. Toto analysis methods serve as guides within this randomness, helping players make more informed choices.
9. Psychological Considerations: Avoiding Common Number Selections
Human psychology often influences number selections in Toto. Analysis methods take into account common player tendencies, such as choosing birthdays or anniversaries, and aim to guide players toward less frequently selected numbers. This strategic move can potentially reduce the likelihood of sharing prizes in the event of a win.
10. Responsible Gaming: Setting Limits and Expectations
As players engage with Toto analysis methods, it’s crucial to emphasize responsible gaming. Setting realistic expectations, establishing budgetary limits, and viewing Toto as a form of entertainment rather than a guaranteed source of income contribute to a healthier and more enjoyable gaming experience.
Navigating the Toto Landscape with Analysis Wisdom
In the realm of Toto, where chance and strategy intersect, analysis methods serve as valuable tools for players seeking a more calculated approach to number selection. By understanding statistical patterns, leveraging wheeling systems, and embracing the unpredictability of randomness, players can navigate the Toto landscape with wisdom and strategy. It’s essential to approach Toto with a balanced mindset, combining analytical insights with responsible gaming practices for an enriched and enjoyable experience.


Willem van Zwet made deep and influential contributions to probability and statistics, which we review in this paper. Bickel and Götze collaborated with him on his major contributions to higher order asymptotics of nonlinear statistics and on resampling and the bootstrap. We relate this work to his remarkable development of the properties of the Hoeffding expansion for symmetric statistics as well as Fourier analytic tools. Fiocco and De Gunst were his students. We describe how in their theses and subsequent papers with him they developed statistical inference in two subtle stochastic models, the contact process and cell population development under a plausible regime. We also touch on his solutions of intriguing problems not related directly to his main interests.

On Wednesday, the Minister of Education, Jean-Michel Blanquer, announced the return of mathematics to the common core of high school students at Première and Terminale, from the start of the next school year. Since baccalaureate reform in 2019, math is no longer taught to all high school students. Students who chose the math specialty followed a four -hour per week course. For others, only “scientific education”, which combines physics, science and terrestrial life and mathematics, is given two hours per week.
“We’ve already done everything we can to organize the system for the next school year, with 3.5 hours of science and math in the common core for those who don’t do specialty science education,” Jean-Michel Blanquer said in RTL Wednesday. In recent months, calls have increased to return math to the mainstream curriculum.
Emmanuel Macron even made a campaign commitment for his re-election. In mid-March, a report submitted by the government called for adding from next September 1h30 to 2 hours of math to the timetable of non-specialist high school students. Realizing, this announcement made by the press shocked the teaching unions, three months before the start of the school year.
“Lack of respect for students”
“We can only be content with the fact of adding mathematics to the program for all students, but it will speed up over time,” said judge Sébastien Planchenault, president of the Association of Mathematics Teachers in Public Education (APMEP). thoughtful, more rational. “We consider this an urgent measure that has contributed to the deterioration of a failed reform”, said Alexis Torchet, national secretary of the General Union of National Education Sgen-CFDT.
Second -year students, who will be the first to be affected by this reform, are already making their special wish. “We support students, families, we’ve been working on these options since the beginning of the year, so it’s hard to change the rule of the road. It’s a lack of respect for students, families and the community. to teach, ”considered Olivier Beaufrere, national secretary of Snpden-Unsa, the management staff union.
No details were provided by the ministry on how math was calculated for the baccalaureate, or the impact that this return to the common core had on the options for Superior. “We already have parents wondering if, because math has a common core, it is necessary for their child to choose a math specialty. It presents difficulties in terms of orientation and establishment leaders struggle to respond, “observes Alexis Torchet.
An unbalanced common core
However, they all point to the need to change the area of math and science in high school students ’programs. “The common core is not very balanced between the core of science and the core of literature and human science, analyzes Alexis Torchet. We consider it necessary to change all the core of the common core”. The unions want a real reflection, with an implementation at the start of the school year in 2023. in a hurry that no reason can do, ”Oliver Beaufrere lamented.
Especially since the purposes of this mathematics education are unclear. “At 1h30, we need to allow students to reconnect with teaching math, allow them to have enough background for understanding the world and this teaching should also be enough to follow the complementary terminale math option, which is based in a four -hour first -year specialty program. It’s insolvent, ”Sébastien Planchenault pointed out.
Lack of math teachers
Especially if another problem arises. Schools suffer from a severe shortage of math teachers. According to figures from the last Capes, the teacher competition, 816 candidates qualified in math for 1,035 open positions. “There is great concern. Recruitment is already difficult in the current arrangement. We risk not having teachers that match expectations, or else we will have to devote a lot of time away from other lessons, ”Oliver Beaufrere analyzes.
“We need a real policy related to the recruitment of teachers to meet the needs: salary increases, scholarships to support students to pass the competition, improve the image of the profession itself, believes Sébastien Planchenault. But since there is no sustainable solution, in the short term, it will mean overtime for math teachers and hiring contract workers, with the risk of no teaching. High quality “. In front of the press, the school’s director general of education, Edouard Geffray, wanted to assure: “students have a teacher in front of them at the next start of the school year”.


You can see why the free odds bet is such a great one and why some of the proposition bets are terrible. My advice is to study this information or at least glance at it to find good strategies. Visit for the online version of this bet calculator handling the same wide variety of options. In order to calculate the profit, all you have to do is subtract your wager amount from the calculated payout.

To calculate fractional odds, you have to do some mental division or enter your desired amount and see what the sportsbook shows as your payout. Here are some odds for a fictitious horse race and how you’d go about reading them. Understanding how to read odds is crucial to betting on sports.
How To Calculate Parlay Betting Odds?
It’s critically important because it allows you to understand how likely an event is to happen, and what your potential winnings will be. But read this betting odds explained guide to help to understand. The odds that bookmakers and casinos set aren’t usually calculated from the mathematical probability that certain events will occur.
They can be complex to understand for a newcomer, but once you understand the basics, you’ll be betting like a pro. We have a number of odds calculators on our site for various types of bets, including moneyline, parlay, and futures calculators. Odds calculators help you determine what your payout would be if you were to make a specific bet.
You can then compare the probability you give the bet of winning against the probability that the Bookies think it will win by calculating the Implied Probability of the odds. This will enable you to see whether there is value in the bet or not. Using this kind of system will allow you to determine whether the risk is worth the reward. You just put in the stakes, the odds and the type of bet and then you will immediately see your calculation when you hit the button. On multiple bets, you will be able to see on your betting slip, the different potentials. To calculate the implied probability of Golovkin winning the fight, take the number of times he is expected to win and divide it by the total number of trials .
Place A Bet
The payout for each winning parlay is the same as it would be if the parlay bets were each made individually. Since that’s incredibly obvious, sportsbooks have blocks in place to prevent you from betting these parlays. Recently, “same-game parlays” have become a phenomenon in sports betting. But be warned, you must check the payouts on these before booking them and see how they compare to the individual bets parlayed together.

Then that one quote will be converted into the other odds format that are available in the calculator. That includes Decimal and Fractional, along with the Hong Kong and Indoneison formats. To convert odds with the betting odds calculator, you simply enter the odds quoted in the relevant box in the calculator and click the Convert button. Odds for sporting events can get quite complex, especially for those new to sports betting. Combining different odds for different events can get even more confusing. A Canadian betting winnings calculator works out the returns of your winnings when placing a bet on five selections.

A note on submanifolds of generalized Kähler manifolds
In this note, we consider submanifolds of a generalized Kähler manifold that are CR-submanifolds for the two associated Hermitian structures. Then, we establish the conditions for the induced, generalized F structure to be a CRFK structure. The results extend similar conditions which we obtained for hypersurfaces in an earlier paper.

How We Teach Maths - Implementation
- We have developed our own long-term plans, based on the National Curriculum outcomes for each year group (see Year Group Expected Outcomes), which are delivered through daily Maths lessons.
- Based on the Mastery Approach (see Maths Mastery), lessons are carefully sequenced around the CPA Approach and learning is scaffolded in order to support and embed understanding for all children.
- A range of Concrete Materials, (see CPA Approach) including number beads, Numicon, Dienes, ten frames, place value counters, multilink and Cuisenaire are used to support children’s Mathematical understanding through the use of practical opportunities to model concepts. Pictorial representation (see CPA Approach) are used alongside these materials and include slides from our Visual Calculations Policy (see page)
- Vocabulary is used in context to help children develop a real understanding of Mathematical language.
- ICT is used to support learning in a variety of ways: through interactive presentations and games/songs and online learning platforms such as Mathletics at KS2. (see Learning Zone under Parents/Carers Tab)
- Opportunities for children to discuss, to use and apply skills, to problem solve and reason, form the basis of our teaching. These activities present a level of challenge for children who are encouraged to develop skills such as resilience, perseverance, trial and error and a ‘can do’ attitude. (see Maths Mastery page)
- Daily on-going assessment of learning supports immediate feedback to children and opportunities address misconceptions and identify and correct mistakes within a lesson. (see Feedback/Marking in Maths page)
- Daily 4-a-day (see 4-a-Day page) for children in Yr1 to Yr6 is used to provide regular opportunities to practice, apply and consolidate number strategies for addition, subtraction, division and multiplication which they have already learnt.
- Regular games, songs, activities and opportunities for counting in steps and times tables (see counting/times tables page) are used to support children to learn these skills and facts, alongside our weekly speed grids and x tables badge challenges.
- Opportunites for our families to support at home (see support at home page) with links for this found on our Learning Zone (see under parents/carers tab) weekly and half termly Brainbuilder and workshops (see under parents/carers tab) with ideas for activites and games.
“Achievement Partnership Success”


Data science, blending data with algorithm development and technology to solve complex analytical problems, has been called the sexiest job of the 21st century.
“A data scientist has to understand how to use appropriate tools in a given situation,” says Colleen Hoover, Ph.D., associate professor of mathematics and department chair at Saint Mary’s College in Notre Dame, IN. “They have to be able to dive in and really understand the question being asked and which tools across the fields of mathematics, computer science, and statistics they will need to answer those questions.”
The Bureau of Labor Statistics projects jobs in mathematical science occupations will grow 27.9 percent from 2016 to 2026, (over 50,000 new jobs), much faster than other occupations. Employers need experts to analyze raw data into useful information to solve modern business problems.

Joint probability analysis is most often conducted within a stationary framework. In the present study a nonstationary bivariate approach is used to investigate the changes in the joint probabilities of extreme wave heights and corresponding storm surges with time. The dependence structure of the studied variables is modelled using copulas. The nonstationary Generalized Extreme Value (GEV) distribution is utilized to model the marginal distribution functions of the variables, within a 40-year moving time window. All parameters of the GEV are tested for statistically significant linear and polynomial trends over time. Then different copula functions are fitted to model the dependence structure of the data. The nonstationarity of the dependence structure of the studied variables is also investigated. The methods and techniques of the present work are implemented to wave height annual maxima and corresponding storm surges at two selected areas of the Aegean Sea. The analysis reveals the existence of trends in the joint exceedance probabilities of the variables, in the most likely events selected for each time interval, as well as in a defined hazard series, such as the water level at the coastline.

Assumption of Normality
A distribution is skewed if it has one fat tail (has a greater than normal proportion of extreme scores in one tail only). The formula for measuring skewness in the sample is:
All scores are changed into z scores, then cubed, and the statistic (g1) equals the mean of the cubed z scores. Note this has two important attributes:
Because they are cubed, any large z scores (i.e. outliers) have a big effect on the statistic.
Cubing a value retains its sign, so if there is a large positive z value (an extreme score above the mean, say z=3.1 so z cubed equals 29.79)
also a large negative z value (an extreme score below the mean, say z=-2.9, so z cubed equals -24.38) they more or less cancel each other out. So g1 can only be a value far from zero if most of the extreme scores are off in one direction only (i.e. the data are skewed). If the data are perfectly symmetrical then g1=0.
The formula given above is for measuring the skewness of the
(i.e. it is a statistic). What we wantto know, however, is the skewness of the
(the parameter), for the assumption of normality has to do with the shape of the population. g1 is a biased estimate of the skewness of the population. As with the variance, a slight adjustment is needed to the formula to estimate the parameter. So which does SPSS give you when it reports a value for ‘skewness’, the statistic or the estimate of the parameter?
Most statistics books give the formula I gave above (the statistic). SPSS gives you the estimate of the parameter, which is good because that is what you want. The point, however, is that information on which formula is used in computing a value provided by a statistics program is hard to come by. You won’t find this information in the SPSS help menu or in many of the books about SPSS. This is one of the challenges of using a statistics program, finding out exactly what it is computing. For SPSS I have found the book by
to be most informative.
Back to skewness. If the data are negatively skewed then the value of g1 will be negative, if the data are positively skewed then the value of g1 will be positive. The more skewed the data the bigger the absolute value of g1, but how big does g1 have to get to be worthy of your attention? Gardner suggests turning g1 into a standard score, which we know how to interpret.
SPSS will give you the value of skewness (estimate of skewness in the population) and the standard error that goes with it. The mean of the population of skewness scores if the data are symmetrical (i.e. if H0 is true) is zero. With that information you can calculate the standard score of the skewness, if its absolute value is greater than, say, 2 they you might want to worry (as you can see, this is not a precise thing). The measure of skewness and its standard error are available as part of the SPSS 'Analyze>>DescriptiveStatistics>>Explore' menu item and they also show up unbidden in the output of various other procedures.
: this sample was drawn from a normal population, which is a symmetrical distribution, and thus the absolute value of the standard score of the measure of skewness should be low.
Skewness=-.04 Std Error=.241
Negatively Skewed Distribution
: this sample was drawn from a negatively skewed population and thus the standard score of the measure of skewness should be a large negative number.
Skewness=-1.161. Std Err=.229
: this sample was drawn from a fat-tailed population, which is a symmetrical distribution, and thus the absolute value of the standard score of the measure of skewness should be low.

I'm working through the "Measuring the Value of Information" chapter in Hubbard's How to Measure Anything and am puzzled by the example in "The Value of Information Ranges" section (starting on page 89 of the first edition).
Here's what I'm doing:
Based on the givens, I create a normal distribution with mean of 550,000 and an SD of 273,556 (this gives a 90% CI between 100,000 and 1,000,000). For the opportunity loss of a slice, I'm using:
25*(200,000-j) where j is the mid-point of a slice.
The probability of a slice is computed using the normal distribution mentioned above. I'm pretty sure this is all correct, but please let me know if I've screwed it up!
At this point I'm unsure about which range I should cut into slices.
Originally I used [0, 200,000]. I reasoned that the scenario was focused on the number of additional units sold due to the ad campaign, and the text seemed to indicate that zero additional sales was the lower limit: "If we didn't sell any, we would have lost the cost of the ad campaign, $5 million (you might say the business would lose more than jus the cost of the campaign, but let's keep it simple). However, the computed EVPI in this case comes to $157,647.
If, instead, I slice up the interval -1,500,000 to 200,000, I get an EVPI of $323,090. This is close enough to the value given in the book, $337,500, that I'm tempted to attribute the difference to slicing variances. But I'm not sure why, in this case, it makes sense to include the portion of the tail less than zero. So I doubt this is correct.
If anyone has insight on this, please drop me a line. I'm probably missing something obvious about the method.


Following is the list of 10 metrics which we’ll study in an interconnected way through examples:
- Confusion Matrix
- Type I Error
- Type II Error
- Recall or True Positive Rate or Sensitivity
- F1 Score
- ROC Curve- AUC Score
- PR Curve
Once we learn the appropriate usage and how to interpret these metrics according to your problem statement, then gauging the strength of a classification model becomes a cakewalk.
Let’s dive right in!
We’ll be using an example of a dataset having yes and no labels to be used to train a logistic regression model. This use case can be of any classification problem — spam detection, cancer prediction, attrition rate prediction, campaign target predictions, etc. We’ll be referring to special use-cases as and when required in this post. For now, we will take into consideration a simple logistic model which has to predict yes or no.
First things first, a logistic model can give two kinds of outputs:
1. It gives out class labels as output values (yes/no, 1/0, malignant/benign, attrited/retained, spam/not spam etc.)
2. It gives probability values between 0 to 1 as output values to signify how likely or how unlikely an event is for a particular observation.
The class labels scenario can be further segmented into the cases of balanced or imbalanced datasets, both of these cannot be judged/should not be judged basis on similar metrics. Some metrics are more suited for but not another and vice-versa. Similarly, the Probabilities scenario has different model performance metrics than the class labels one.
Following is the flowchart which is a perfect summary as well as a perfect preface for this post, we will revisit this flowchart once again at the end to make sure we understand all the metrics.
1. Confusion Matrix
We start with a development dataset while building any statistical or ML model. Divide that dataset into 2 parts: Training and Test. Keep aside the test dataset and train the model using the training dataset. Once the model is ready to predict, we try making predictions on the test dataset. And once we segment the results into a matrix similar to as shown in the above figure, we can see how much our model is able to predict right and how much of its predictions are wrong.
We populate the following 4 cells with the numbers from our test dataset(having 1000 observations for instance).
- TP (True-positives): Where the actual label for that column was “Yes” in the test dataset and our logistic regression model also predicted “Yes”. (500 observations)
- TN (True-negatives): Where the actual label for that column was “No” in the test dataset and our logistic regression model also predicted “No”. (200 observations)
- FP (False-positives): Where the actual label for that column was “No” in the test dataset but our logistic regression model predicted “Yes”. (100 observations)
- FN (False-negatives): Where the actual label for that column was “Yes” in the test dataset but our logistic regression model predicted “No”. (200 observations)
These 4 cells constitute the “Confusion matrix” as in the matrix which can alleviate all the confusion about the goodness of our model by painting a clear picture of our model’s predictive power.
A confusion matrix is a table that is often used to describe the performance of a classification model (or “classifier”) on a set of test data for which the true values are known.
2. Type I Error
A type 1 error is also known as a false positive and occurs when a classification model incorrectly predicts a true outcome for an originally false observation.
For example: Let’s suppose our logistic model is working on a spam-not spam email use case. If our model is labeling an otherwise important email as spam then this is an example of Type I error by our model. In this particular problem statement, we are sensitive towards reducing the Type I error as much as possible because important emails going into the spam email can have serious repercussions.
3. Type II Error
A type II error is also known as a false negative and occurs when a classification model incorrectly predicts a false outcome for an originally true observation.
For example: Let’s suppose our logistic model is working on a use case where it has to predict if a person has cancer or not. If our model labels a person having cancer as a healthy person and misclassifies it, then this is an example of Type II error by our model. In this particular problem statement, we are very sensitive towards reducing the Type II error as much as possible because false negatives in this scenario may lead to death if the disease goes on to be undiagnosed in an affected person.
Now, the above three metrics discussed are General-purpose metrics irrespective of the kind of training and test data that you have and the kind of classification algorithm yu have deployed for your problem statements.
We are now moving towards discussing the metrics which are well suited for a particular type of data.
Let’s start talking about Accuracy here, this is a metric that is best used for a balanced dataset.
As you can see, a balanced dataset is one where the 1’s and 0’s, yes’s and no’s, positive and negatives are equally represented by the training data. On the other hand, if the ratio of the two class-labels is skewed then our model will get biased towards one category.
Assuming we have a Balanced dataset, let’s learn what is Accuracy.
Accuracy is the proximity of measurement results to the true value. It tell us how accurate our classification model is able to predict the class labels given in the problem statement.
For example: Let’s suppose that our classification model is trying to predict for customer attrition scenario. In the image above, Out of the total 700 actually attrited customers (TP+FN) , the model was correctly able to classify 500 attrited customers correctly (TP). Similarly, out of the total 300 retained customers (FP+TN), the model was correctly able to classify 200 retained customers correctly (TN).
Accuracy= (TP+TN)/Total customers
In the above scenario, we see that the accuracy of the model on the test dataset of 1000 customers is 70%.
Now, we learned that Accuracy is a metric that should be used only for a balanced dataset. Why is that so? Let’s look at an example to understand that.
In this example, this model was trained on an imbalanced dataset and even the test dataset is imbalanced. The Accuracy metric has a score of 72% which might give us the impression that our model is doing a good job at the classification. But, look closer, this model is doing a terrible job out of predicting the Negative class labels. It only predicted 20 correct outcomes out of 100 total negative label observations. This is why the Accuracy metric should not be used if you have an imbalanced dataset.
The next question is, then what is to be used if you have an imbalanced dataset? The answer is Recall and Precision. Let’s learn more about these.
5. Recall/ Sensitivity/ TPR
Recall/ Sensitivity/ TPR (True Positive Rate) attempts to answer the following question:
What proportion of actual positives was identified correctly?
This metric gives us 78% as the Recall score in the above image. Recall is generally used in use cases where the truth-detection is of utmost importance. For example: The cancer prediction, the stock market classification, etc. over here the problem statement requires that the False negatives be minimized which implies Recall/Sensitivity be maximized.
Precision attempts to answer the following question:
What proportion of positive identifications was actually correct?
The example shown in the above image shows us that the Precision score is 75%. Precision is generally used in cases where it’s of utmost importance not to have a high number of False positives. For example: In spam detection cases, as we discussed above, a false positive would be an observation that was not spam but was classified as Spam by our classification model. Too many of the false positives can defeat the purpose of a spam classifier model. Thus, Precision comes handy here to judge the model performance in this scenario.
Specificity (also called the true negative rate) measures the proportion of actual negatives that are correctly identified as such.
Building on the same spam detection classifier example which we took to understand Precision. Specificity tells us how many negatives our model was able to accurately classify. In this example, we see that specificity =33%, this is not a good score for a spam detection model as this implies majority of non-spam emails are getting wrongly classified as spam. We can derive the conclusion that this model needs improvement by looking at the specificity metric.
8. F1 Score
We talked about Recall and Precision in points numbers 6 and 7 respectively. We understand that there are some problem statements where a higher Recall takes precedence over a higher Precision and vice-versa.
But there are some use-cases, where the distinction is not very clear and as developers, we want to give importance to both Recall and Precision. In this case, there is another metric- F1 Score that can be used. It is dependent on both Precision and Recall.
In a statistical analysis of binary classification, the F1 score (also F-score or F-measure) is a measure of a test’s accuracy. It considers both the precision p and the recall r of the test to compute the score
Before moving to the last two metrics, the following is a good summary table provided on Wikipedia that covers all the metrics we have discussed until now in this post. Zoom in to see if the image seems unclear.
Now, we are at the last leg of this post. Until now we have discussed the model performance metrics for classification models that predict class labels. Now, let’s study the metrics for the models which operate basis on the probabilities.
9. ROC Curve- AUC Score
Area under the Curve (AUC), Receiver Operating Characteristics curve (ROC)
This is one of the most important metrics used for gauging the model performance and is widely popular among the data scientists.
Let’s start understanding this with an example. We have a classification model that gives probability values ranging between 0–1 to predict the probability of a person being obese or not. Probability score near 0 indicates a very low probability that the person under consideration is obese whereas probability values near 1 indicate a very high probability of a person being obese. Now, by default if we consider a threshold of 0.5 then all the people assigned probabilities ≤0.5 will be classified as “Not Obese” and people assigned probabilities >0.5 will be classified as “Obese”. But, we can vary this threshold. What if I make it 0.3 or 0.9. Let’s see what happens.
For simplicity in understanding, we have taken 10 people in our sample.
To plot a ROC curve, we have to plot (1-Specificity) i.e. False Positive Rate on x-axis and Sensitivity i.e. True Positive Rate on the y-axis.
ROC (Receiver Operating Characteristic) Curve tells us about how good the model can distinguish between two things (e.g If a patient is obese or not). Better models can accurately distinguish between the two. Whereas, a poor model will have difficulties in distinguishing between the two.
We’ll see 4 different scenarios wherein we are going to select different values of the threshold and will calculate corresponding x and y-axis values for the ROC curve.
Now, we have 4 data points with the help of which we’ll plot our ROC Curve as shown below.
Thus, this is how ROC Curves can be plotted for a classification model by assigning its different thresholds to create different data points to generate the ROC Curve. The area under the ROC curve is known as AUC. The more the AUC the better your model is. The farther away your ROC curve is from the middle linear line, the better your model is. This is how ROC-AUC can help us judge the performance of our classification models as well as provide us a means to select one model from many classification models.
10. PR Curve
In cases where the data is located mostly in the negative label, the ROC-AUC will give us a result that will not be able to represent the reality much because we primarily focus on a positive rate approach, TPR on y-axis and FPR on the x-axis.
For instance, look at the example below:
Over here you can see that most of the data lie under the negative label and ROC-AUC will not capture that information. In these kinds of scenarios, we turn to PR curves which are nothing but the Precision-Recall curve.
In a PR curve, we’ll calculate and plot Precision on Y-axis and Recall on X-axis to see how our model is performing.
That’s it! We have reached the end of this post. I hope it was helpful.

Middle School Mathematics Sequence:
Information for Parents
Nebraska’s new College and Career Ready Standards for Mathematics have increased the rigor and expectations for students in middle school mathematics courses.
In previous years, the need for multiple levels of Pre-algebra and Algebra courses existed to meet the needs of some students. With these updated state standards, the rigor of mathematics content in 7th grade better meets the needs of some of the students previously placed in the Pre-Algebra course that included some 8th grade content.
The raised expectations in 7th grade lead to an 8th grade course that provides better preparation for high school Algebra and Geometry than in past years. Much of the content previously covered in Math 8 was heavy on repetition of 6th and 7th grade content, this is no longer the case with the new 8th grade standards.
This change in standards creates a need for the restructuring of mathematics courses at the middle school level.
- While the 6th grade math courses will not see significant changes in content or structure, the courses that 6th grade teachers recommend their students take the following year will be different.
- Students in 7th grade will take either Course 2 or Course 2 Diff. Course 2 will cover the state mathematics standards for 7th grade and Course 2 Diff will cover the 7th grade standards and some 8th grade standards in preparation for Algebra in 8th grade and Geometry in 9th grade. Those students that typically found success in Pre-algebra will now take Course 2 Diff.
- In 8th grade, students will take Course 3, which covers the 8th grade standards, or they will take Algebra Diff.
Enrollment in Differentiated level courses is open to all students who demonstrate a high level of understanding and is maintained based on student achievement.
This restructuring will allow teachers to better support those students that have either struggled with math or that have excelled. At the same time, reducing the number of courses offered will simplify the course recommendation process and provide for more appropriate course placement.
Starting in the 2018-2019 school year, the middle school mathematics course sequence will be adjusted and the courses will have new names that will clarify when a course is offered. The goal is for students to be in the math course that provides opportunity to be both challenged and successful.

We consider the issue of estimating the prevalence of a disease under a group testing framework. bias. In this article we propose simple designs and methods for prevalence estimation that do not require known values of assay sensitivity and specificity. If a gold standard test is available it can be applied to a validation subsample to yield information on the imperfect assay’s sensitivity and specificity. When a gold standard is unavailable it is possible to estimate assay sensitivity and specificity either as unknown constants or as specified functions of the group size from group testing data with varying group size. We develop methods for estimating parameters and for finding or approximating optimal designs and perform extensive simulation experiments to evaluate and compare the different designs. An example concerning human immunodeficiency virus infection is used to illustrate the validation subsample design. = P(subjects (with disease status = 1) = 1 ? (1 ? (1 if positive; 0 if negative). Writing Se = P(= 1|= 1) and Sp = P(= 0|= 0) for the assay’s sensitivity and specificity respectively we then have can be identified as YM201636 (= 1 … is then given by is adjustments can be made. For large and variance YM201636 may be chosen by minimizing expression (3) for a fixed (and the optimal will not depend on = (total number of subjects) in which case in (3) will be replaced by in several scenarios. For a given scenario and a given = 0.05 0.005 and Sp = 0.995 and either fix Se = 0.95 or allow Se to decrease with versus fixed = = 0.05 0.005 and Sp = 0.995 with and without a dilution effect (see Section 2 for details). = (= YM201636 1 which corresponds to the traditional individual testing approach. So the mis-substitution bias is not caused by group testing; rather it is caused by an imperfect assay with unknown sensitivity and specificity. Table 1 shows the limit of the mis-substitution bias (as → ∞) when either or both of Se = 0.95 and Sp = 0.995 are misspecified. Although Table 1 does not explicitly include a dilution effect it does examine the consequences of misspecifying Se. The and the absolute bias for = logit(is usually small it seems YM201636 more sensible to consider the relative bias for than the absolute bias for < Se. When either inequality is violated by the specified YM201636 values of (Se Sp) the standard procedure fails to produce a meaningful prevalence estimate asymptotically. This occurs several times in Table 1 as indicated by the “NA” entries. Specifically we have ≈ 0.0097 < 0.01 = 1 ? Sp* when = 0.005 = 1 and Sp* = 0.99 and ≈ 0.9496 > 0.9 = Se* when = 0.05 = 150 and Se* = 0.9 where Sp* and Se* are misspecified values. Table 1 KLRK1 The mis-substitution bias: relative bias for and absolute bias for = logit(→ ∞ (see Section 2 for details). … 3 The VS Design (With a Gold Standard Available) 3.1 Basics Suppose a gold standard test is available but too expensive to apply to the entire sample. We propose to apply the gold standard to a subsample of pooled specimens selected in a manner that may depend on the test results (= 1 if the = 1 implies that is observed. The assumed sampling mechanism for the VS implies that the positive and negative predictive values can now be identified as are not identically 0 or 1 in the VS. Because the probability = P(= 1) is trivially identifiable we can now identify the joint distribution of (is defined in Section 2 and converges as → ∞ to a normal distribution with mean 0 and variance where Ivs is the Fisher information for ((see Web Appendix A for explicit expressions). In particular and variance and the VS sampling mechanism as characterized by = P(= 1|= = 0 1 for given values of (or (ii) fixed = or would be appropriate if the cost of the imperfect assay is negligible in comparison to the cost of enrolling a subject while a fixed would be appropriate in the opposite situation.

How many golf balls fit in a school bus interview question?
So, when we divide 1.6 cubic inches by 2.5 cubic inches we get 660,000 balls. Since a school bus is not empty and has some space occupied by the engine and seats, it is best that we round off this figure to 500,000. This means that a school bus can accommodate 500,000 golf balls.
How many golf balls can you fit into a Boeing 777?
Battison: But if we have an airliner, we do have those seats that can ‘t hold the golf balls. Josaphat: 56,784 cubic feet divided by 12 cubic feet. That total answer would be 4,732 golf balls.
How many ping pong balls are in a room?
let’s say that a standard room has a length of 7m width of 4m and a height of 2.5m. and the diameter of a pingpong ball is 4cm or 0.04m. Fitting pingpong balls into room = volume of room / volume of pingpong ball. = 1,567,164 ping pong balls.
How many golf balls fit into a Boeing 747?
The question is fairly satisfactorily answered: “The 747-400 has a passenger volume of 876 cubic meters, plus a cargo volume of 159 cubic meters, for a total of 1035; the balls have a diameter of 40mm; this gives about 22,870,000 ping pong balls.”
How many tennis balls can fit in a limousine?
To get the total number of tennis balls that will fit into a limo, we need to divide the volume of the limo (500,000 cubic inches) by the volume of a tennis ball (4 cubic inches); 500,000/4 = 125,000. Now, we can say that 125,000 tennis ball will fit in a limousine.
How many golf balls are on the moon?
There are two golf balls on the moon. They were taken there by Alan Shepard in 1971, during the Apollo 14 mission. Shepard was the first American into space, and the fifth person to ever walk on the moon … but most impressively, he was the first (and only) person to ever play golf outside of the earth’s atmosphere!
How many golf balls can you put in a 5 gallon bucket?
The math suggests, a spherically sized bucket can contain around 340 balls, although, usually golfers use a 5 – gallon bucket to carry an average of fifty to eighty balls in or out of the golf pitch.
How many balls fit in a Mini Cooper?
Now for the number of tennis balls which can fit in Mini Cooper. We need to divide by 4. Round up to 140,000, as it’s easier to divide by 4, so 140,000 /4 is 35,000.
How many golf balls will fit in the Empire State Building?
25,780,645,161 balls. This of course disregards the irregularity of the structure and assumes the 37 million cubic feet is a volume of a simple box.

Our Featured event for the week is the ZetaTrek Expedition, an online event organized by Rohit Gupta. In this guest post, Rohit updates us on the mysteries that his team of 21 participants has set out to explore.
Update From The ZetaTrek Expedition:
Ancient mysteries continue to haunt the team of 21 participants from 7 countries who have joined this quest thus far. More than two thousand years ago, for instance, the Greeks realized that the number 496 is a sum of its own proper divisors:
496 = 1 + 2 + 4 + 8 + 16 + 31 + 62 + 124 + 248
Such a number they called a perfect number. Till this day, we do not know whether there is an infinite number of them. All the 47 known perfect numbers until the year 2011 are also even (multiples of 2), the largest number having 25956377 digits. Nor do we know if there exists a perfect number which is odd. We know that if an odd perfect number exists, it is many orders of magnitude larger than the estimated number of atoms in the observable universe. Another elementary observation, 496 is also the sum of all numbers below 31.
496 = 1 + 2 + 3 + 4……28 + 29 + 30 + 31
Here is a snapshot from the opening pages of the monumental book by
L. E. Dickson, History Of The Theory of Numbers Vol. I ( 1919 edition):
In 1984, it was discovered by physicists Michael Green and John Schwarz that superstring theory only makes sense if the dimension of a certain “gauge group” is the number 496. The link between numbers and cosmology that originated in mystical thought eons ago continues to bedazzle us today.
