Modeling Under Uncertainty
In this course, we will learn how to model randomness, analyze its impact and make optimal decisions when it is present. We will cover stochastic modeling techniques, statistical principles, simulation, and decision-making under uncertainty. Using applications, we will demonstrate how we can use statistical principles to gain insight from data generated by systems with randomness. We will use simulation models to assess the performance of such systems and gauge how it changes in response to our decisions. We will intorudce and use stochastic modeling techniques, such as Markov chains and Brownian motion, to build models of random phenomena and use these to gain understanding and guide decisions. As well as covering theoretical concepts, the course will put substantial emphasis in computaitonal implementation of both simulation and decision-making problems.

The term “Experimental Mathematics” is not made use of to describe an imaginary mathematical study that may be performed by a young youngster in an elementary school
it is used to describe the application of a systematic and special way of teaching mathematics. Inside the 1950’s, mathematicians were debating about what tends to make for any superior teacher and there was no clear answer.
There was also many confusion amongst these mathematicians who had a lot more encounter in teaching mathematics. A preferred opinion held that the good results of a teacher rested solely on the competence of that teacher. These mathematicians who did not come from teaching backgrounds believed that write my essay the results of a teacher could be observed in his achievements in greater mathematics, that may be mathematics for all those that have had excellent teaching backgrounds, as an alternative to the student achievement as measured by the standardized test scores of a specific topic.
Mathematical talent may be developed in any child. It doesn’t matter in the event the child has been told nothing at all concerning the topic. The fascination with mathematics will naturally show itself in the child’s mathematical potential. An understanding in the mathematical language also assists the child to communicate his mathematical complications in an understandable way.
The ability to find out is certainly a very important factor but in addition of considerable help to the kid to create in mathematics. But the child may also have the ability to draw a logical connection amongst the symbols and meanings he learns and those that are used to solve true life complications.
Experimental mathematics requires the fact that mathematics is generally produced to become “complicated” and attempts to offer a mathematical education that is rather much more simple. http://en.wikipedia.com/wiki/Biostatistics The class will commence with standard ideas, for instance color, numbers, space, time, angle, plus the like. Teachers will try to involve the child in all of the ideas, keeping him as involved as you can.
The school will generally take a range of various locations of mathematics. They may use something like wordsearch or geometric optimization as an instance. The kid will likely be allowed to utilize his personal ideas moreover towards the teacher’s concepts to resolve complications.
The child may effectively discover that the tests are much harder than they will be inside a standard classroom setting. Certainly one of one of the most fascinating ewriters pro components with the experiment is that the teachers along with the student will interact incredibly tiny with one another. Nobody will recommend techniques to improve the child’s overall performance.
Experimental mathematics is a matter of following a set of rules and procedures, in lieu of deciding what ideas would work. Instead of a large quantity of students, the teacher will have a compact group of students to test. The very best test of the experimental formula can only be determined following it has been utilized for any even though.
The essential to success is to pick a fairly modest group of students for the experiment. The group chosen for this goal ought to be fairly modest. The class really should contain some kids with considerable mathematical talent and a few kids with substantial lack of mathematical potential.
The general teacher evaluation will contain the child’s ability to master a certain topic, his progress over the year, and also a survey of the students’ grades. These will include things like general information as well as the student’s capability to find the meaning of each day objects and the order in which they should be arranged. Tests in the students’ mathematical reasoning expertise may also be offered.
The most important issue that may be mentioned is that the child will not get an extremely high grade. The higher the child’s grade, the much better his probabilities of having into the most competitive colleges within the nation.


Purdue University program named among top in country for preparing future elementary math
Program Earns National Recognition for Robust Requirements in Key Elementary Mathematics Content and Pedagogy
West Lafayette, Indiana—The undergraduate elementary teacher preparation program at Purdue University has been named among the best in the nation when it comes to ensuring future elementary teachers have the essential content and skills they need to teach mathematics. The National Council on Teacher Quality (NCTQ), a national research and policy organization that regularly evaluates the core requirements and practices of over 1,100 programs that prepare future elementary teachers released a new report today in which the undergraduate program at Purdue University earned an A for its requirements in elementary mathematics.
NCTQ evaluated programs for their coverage of both the key mathematics content that elementary teachers need: Numbers and Operations, Algebraic Thinking, Geometry and Measurement, and Data Analysis and Probability, as well as how to teach those concepts (Math Pedagogy). The recommended minimum instructional time that future elementary teachers need in these essential math topics was set based on guidance NCTQ received from teacher preparation programs, mathematicians, and math educators as part of an Expert Panel. Purdue University stands apart by meeting 90% or more of the instructional goals across each of the elementary mathematics topic areas.
Research studies have found that elementary math skills are a strong predictor of whether or not a student will graduate from high school. Recent data has found that students in many states have lost more learning in math than in reading over the past two years and pre-existing gaps in math achievement have worsened since 2020 between low-poverty and high-poverty schools and between majority-White and majority-Black schools, so the need for elementary teachers to be well-prepared to teach mathematics has never been more urgent.
“We know how much math matters in setting a foundation for students,” said Dr. Heather Peske, NCTQ President. “The biggest in-school difference we can make for students’ math learning is to make sure their elementary teachers understand key math content and know how to teach math effectively. Purdue University should be proud to be among the top teacher preparation programs in the country working towards this goal.”

“Math is fun. MATH IS FUN!” I regularly say, shout, chant, and sing to my kiddos.
What they’ll never hear me confess is: “I’m not a math person,” “Some people just aren’t good at numbers,” or “I’m bad at math.” All thoughts I’ve 100% had.
Why this double-life? Because I want my kids to relish numbers.
I want them to dig puzzles and problems. I want them to jump right on board that train traveling 80 mph, heading toward Easton, 260 miles away and wave at some other train, traveling 50 mph, that leaves Easton heading toward Weston. I want them to delight in knowing when the two trains meet and how far from each city they are when they meet! I am teaching my kids to love math because it is a crime that I don’t.
I am completely capable of doing math, I just doubt my abilities on a daily basis. Whenever I calculate tips in restaurants, I always double check myself against the little tip card I carry in my wallet. When something’s on sale at a store, I never trust the deal, calculating over and over how much I really must be saving. These little things can add up too. A few years ago, I wanted to roll my mutual fund over into a lower fee account, but I let my financial advisor talk me into staying with the higher fee even though I KNEW it was costing me more money. And while I make a good living, I cringe when I see what I might be making if I’d pursued a career that uses math. It’s ridiculous how much my fear and doubts about math have held me back in little ways and big. This is why I’ve taken steps to hide my fears about math; I want more for my girls.
Want to join me in my subterfuge? Here’s how:
Model Math Positivity: Tell Your Kids that You Love Math
Have you ever heard someone say they weren’t good at reading? No? Chances are, you’ve heard plenty of people say that they weren’t good at math. For some reason, it’s socially more acceptable to put down your math ability than it is your reading skills. People have no problem publicly mocking another person’s math skills when they’d never joke about your reading level. Our readiness though to point out someone else’s or confess so easily to being innumerate ourselves may be a big problem. Thinking that we’re not good at math can make us- wait for it- less good at doing math. And the more other people say they’re not good at math, the easier it is for us to believe that math is hard.
Growing up, I saw my older brother and both of my male younger cousins doing well in the subject I struggled with in the same schools, and I didn’t get it. How did I miss the math gene that they so obviously got? Was it because I was a girl?
The truth is that there is no math gene and that girls can achieve equally well at math. We can all be good at math if we work at it. My brother and my cousins were good at math because they worked at it and because they saw plenty of male role models doing math. And while I wasn’t a slacker, when math got hard for me, it was just easier to say I wasn’t good at it and that I hadn’t been born “gifted” as they had been. Not seeing a lot of professional women using math probably didn’t help either.
A few years back, my aunt shared that she always tried to promote math with my cousins. They never heard her say math was hard or that she couldn’t do it. Instead, she declared a passion for math and spoke positively any time the subject came up. Our kids take their cues for how to think about things from us, which is why I’m following my aunt’s example with my two girls, genes and gender aside. We read books about math, I point out all the women we know who work in finance or math or science. When Libby was puzzling for what to name her new stuffed polar bear, I suggested Ada for Ada Lovelace, the first computer programmer. My girls hear plenty of good things about math from me.
Still doubting your own abilities to stay positive about math? Watch this video from Stanford math professor, Jo Boaler, about how anyone can learn math to a high level. Now watch it again with your kids!
Do Math and Make it Fun
If the thought of polynomials causes you to break it in a cold sweat, relax. Doing math with your kids, especially when they’re young, is more doable than you think.
For the babes & toddlers:
Count. Count EVERYTHING. Fingers, toes, Cheerios. The girls and I would count our shoes, our books, how many toys we put into the toy basket when they were young. Our ritual of counting the steps going into her pre-school helped get my youngest daughter excited for the school day. You can also identify shapes (early geometry!) and build with your wee ones to promote development of their spatial abilities.
For little kids:
Bake with them. I’ve found no better way to teach fractions than having my girls measure ½ cup of chocolate chips. Measuring cups are essential math tools.
Have fun estimating. Guess how many chocolate chips there are in that ¼ cup and count to verify before eating them. If my kids associate math with fun and chocolate, I count that as a win!
For elementary school kids:
We started doing Bedtime Math with our kiddos around the time they started school. The idea is that we read to our kids to promote literacy, why wouldn’t we want to also do math problems with them to promote numeracy? We signed up to get a daily email of a math problem that we then read at the dinner table with the girls. The problems are always based on some fun story (like this one about a snowboarding crow!) and the answers are right at the bottom for you (whew!).
Do you hate trying to make conversation with your children at the dinner table? Try math problems instead!
We’re also big fans of using the girls’ allowances to teach math. Just yesterday, Libby had to shell out $7 of her own money for the dress she wanted me to buy her. She painstakingly counted out quarters, nickels, and pennies from her wallet. When offered the same deal, her older sister Nell opted to save her money, deciding the shirt she had wanted was “not really worth it.”
For big kids:
Don’t stress your kid’s math homework. Seriously. It’s their homework, not yours. Don’t get me wrong, your student may need support completing homework. Your job though is to offer that support, not the answers to any math problem
Also, try not to slam the Common Core math (I know I may not be making friends on this point!) your kids are learning at school. You may notice that the math work your student is bringing home looks different than what you used to do in schools; trust me, this is a good thing. Students today are learning to think more deeply about the math they’re doing, which means they’re not always solving problems the way we learned how to a century ago. Your student will take their cue from you, so if you can be open to trying to solve problems in a new (and research supported) way, so can your student. Common Core math may not immediately make sense to us, but having our kids teach us can also be a powerful motivating force to encouraging their love of math.
Let Your Kids Make Mistakes
There are plenty of articles about letting your child fail at something these days, and math is no exception. Our brains actually grow more when we make mistakes, so letting your child mess up on their own is a good thing. We like to puzzle through a problem and ask the girls to try to explain why they think what they think. In our house, when Libby figures out a problem too quickly, I apologize for giving her a boring problem: “No fun!” The time we cheer the girls on is when the problem get hard and they stumble. We push them to persist, telling them how the synapses are firing when the math gets hard. Working and failing is learning. Deep learning doesn’t come easy.
All of which leads me to confess something not a single one of my high school math teachers would ever believe: I am such a math nerd. I love math. Seriously, you can ask my kids. They’re getting pretty nerdy themselves, and I wouldn’t have it any other way.


And Nashoba Valley Technical High School in Westford, the district which includes Townsend and Shirley, achieved a scoring average of 1344 on the SAT.
Throughout the state, students averaged 508 on the critical reading section of the test, 524 on the math section, and 504 on writing, for a combined average of 1536. The math score was an improvement of two points over 2009, while scores for reading and writing stayed the same.
Education officials said 75 percent of Massachusetts public school students in the class of 2010 participated in the SAT, ranking the state second in participation behind only Maine.

The Kahn, Saks, and Sturtevant approach to the Evasiveness Conjecture (see the original paper here) is an epic application of pure mathematics to computer science. I’ll give an overview of the approach here, and probably try to add some more information on the problem in other posts.
tl;dr The KSS approach provides an algebraic-topological attack to a combinatorial hypothesis, and reduces a graph complexity problem to a problem of contractibility and (not) finding fixed points.
First, the Evasiveness Conjecture states that any (non-trivial) monotone graph property is evasive. In other words, if you’re trying to figure out whether an undirected n-vertex graph satisfies a certain property (e.g., whether the graph contains a triangle or is connected), and this property is monotone (meaning that if you add more edges to the graph, then it still satisfies the property), then if all you’re allowed to do is ask questions of the form “Is edge (i, j) in the graph?”, then you need to query for every single edge before you can determine whether the graph satisfies the property or not. For example, if you want to figure out whether a graph G contains a clique of size 5, then you need to know whether each of the n(n-1)/2 possible edges is in the graph or not before you can answer for certain.
Next, given any monotone graph property on n-vertex graphs, we can associate it with a simplicial complex S (basically, an n-dimensional structure formed by gluing together a bunch of hypertriangles), by taking the complex to be the set of all n-vertex graphs that don’t satisfy the property.
Kahn, Saks, and Sturtevant then prove that if a monotone graph property is not evasive, then its associated simplicial complex is contractible, and thus (by the Lefschetz Fixed-Point theorem) any auto-simplicial map on the complex (a function from the complex to itself that preserves faces) has a fixed point.
Thus, we can prove that a monotone graph property is evasive by finding a simplicial map that has no fixed point (which we can do by showing that no orbit of the map is a face of the complex). This approach has been used to prove things like the evasiveness of graph properties when the number of vertices is prime or a prime power, and the evasiveness of all bipartite graph properties.


33. Cattle Barons
Down on the Ponderosa the Smith family and the Jones family are heirs to the ranch and all its cattle. They are trying to split the cattle between them but things are getting just a tad complicated...
Al Smith took one steer more than a quarter of the whole lot. Joe Jones took one more than a quarter of those that were left. Pete Smith claimed one more than a quarter of the remainder and Jim Jones took one more than a quarter of those left.
By now the Smith brothers had between them a hundred more cattle than the Jones boys, so Slim Jones took all the rest.
How many cattle did each family end up with?
Scroll down the page for the answer.
OK, we'll call the numbers that each had als, joej, petes, jimj and slimj respectively. If x is the total number of cattle then we have
als = x/4 + 1
now als + petes = joej + jimj + 100
so the total number of cattle was 1020 and the number of cattle for each person was
Al Smith 256
So the Smith family had 400 cattle and the Jones family got 720.

If you make 50% one year and lose 50% the next, you haven’t broken even. You are behind 25%. Here
is an example:
Invest $1000, earn 50%, you now have $1,500
Lose 50% of your $1,500, you are down to $750.
This is because the 50% you lost was half of $1,500, and the 50% you made was half of just the
In a similar way, if you lose 50%, you’ll have to gain 100% just to get back even.
This is the brutal math of investing. The percent of your gains can be wiped out by a smaller


Hi Mikhail, thanks for your feedback. It took me a while to understand the concept but now I think I get it.
- Token amounts should always be represented in uint256, and not in the 64.64-bit fixed point.
- ABDK.Math provides methods like mulu, that takes a uint256 and a 64.64-bit fixed point number and multiplies them, returning a uint256.
- Multiplying a token amount by a decimal number is done with mulu, with the returned value being a token amount in uint256. This covers case 1 of most financial applications.
- The other scenario is dividing a money amount by another, divu takes two uint256 and returns a 64.64-bit fixed point.
You are absolutely right, although there is a limitation on the numbers that can’t be represented in 64.64-bit fixed point, that bears no relationship to the characteristics of the tokens involved, since tokens are always represented in uint256.

This guide will show you how you can crack the code and unlock Arithmancy Door in Hogwarts Legacy.
On the surface, these puzzle doors look like complex math problem numbers and symbols mixed together. And it is too confusing to get it solved.
Arithmancy Doors in Hogwarts Legacy
First, you must need to understand what the outside Archway means. If you get the loot box in the library Annex closet to the Divination Classroom floo Flame point you are just one step ahead. The reason is inside that box there is the key to this puzzle.
How to open Arithmancy Doors in Hogwarts Legacy
In order to solve this puzzle you need to create the number in the middle by finding the animal with the correct numerical value.
For example, you have to find the door with 4 + Snake + ? = 17. So the snake number is 9 and you have to find the question mark number. If we add the 4 and 9 then it is the 13 so we have to find the animal that has the 4 number then it will be the total 17. The number 4 animal is the Owl and it’s the correct answer.
The numbers of all animals are below.
The only thing is to change the corresponding question mark according to the number in the sheet. The door will be opened and the puzzle will be solved.


Ways Students can Overcome Math Problem Solving & Test Anxiety
Math is not the Enemy: Tips on how to overcome Math Anxiety
It is an amazing thing to watch someone with excellent math skill zoom through problems with ease, but many of us struggle to just keep our bank accounts in order. Some of us need help doing the simplest math problems and as soon as we hear the word math, we freeze. Those with great math skills sometimes feel the same way about English and the ability to write well. So what do we do? We buckle down and find ways to help us where we are weak, and when it comes to math there are more of us that need help than meets the eye, (raised hand).
What Teachers Can Do
Math teachers want to know, “What can I do to relieve my student’s anxiety?” Here are a few tips that may help them overcome their fear of tests and actually have a bit more fun with math.
- Math is an exact science. After an answer has been given, invite the class to come up with alternative ways to do the same problem. As in science allow an experiment to develop and have them help each other in groups of 3-4.
- During study time, show them the answers to problems instead of depending on the students that know-it-all to answer. This gets rid of the pit in the stomach feeling that students get that keeps them from raising their hands.
- Gamification of math is an excellent way to teach your students. Allow them to use their calculators as a way to find different paths to the answers. They will learn to be more strategic this way. The majority of people love games, especially students and if math is taught as a game the learning becomes fun.
- After working on specific problems on the board and with the groups, have personal time to allow the calculations that they have just learn sink in.
- Begin confidence building skills by giving students problems that you know they can handle in the beginning of classes. Make the problems look more challenging than they actually are. This will pump up the students’ self-esteem, and as they get more problems right they will feel more motivated to excel in class.
What Can Students Do?
- As a student the best thing you can do for yourself is practice. Anything that you do continually over and over again becomes a part of you. If your teacher assigns 50 problems, find an app that gives you 50 more. If it is the weekend, don’t spend it playing games online, play math games.
- Students need to reach out for help. Your teacher wants to know if you are struggling with your math homework. If your tests are coming back less than passing, you need help. There are tutors available to help you but you must reach out to them and make arrangements for the extra help.
- If you are having trouble understanding your math teacher, request another one. This is appropriate. You are in need of someone that you can understand in order to pass math or any other course of study.
- There's always a way! Find math help online if nohing else works better for you. You won't believe the options available.
We had someone write in that their teacher was from another country other than the U.S. and their accent was confusing. Instead of letting someone know she couldn’t understand, she sat through the entire semester and she failed the class. It is not embarrassing for you to report that you are having trouble understanding the teacher.
We found the following apps that may help with your math problems. They make it fun solving equations and can provide needed math homework help. Check out the tools for math practice:
- My Script Calculator
- Free Graphing Calculator
- CalcBot (this is a calculator)
- Math Ref
What Can Parents Do?
Parents are frustrated as they sit down with their children and try to help them with math they may have never seen.
- If this is your dilemma, contact your students school and let them know that you would like resources that will help you help your student succeed.
- Show your child that you are willing to study along with them, and let them know that this is new to you also. It will be fun for you to learn toghether.
- As you learn together, test each other, laugh at each other’s mistakes saying better luck next time. Continue with this during the entire semester.
- Encourage your student to ask the teacher questions. Let them know that you met with the teacher and she assured you that she would help them.
- Visit the school during the semester to see a sample of their work. Find out their weaknesses and buy appropriate apps and tools to use at home to help them.
By following some of the suggestions listed here teachers and students alike will find that math is not as scary as once thought. There are many websites to help relieve the anxiety that math brings on. Keep on practicing and working towards better outcomes and you will succeed.

About Probability & Statistics
How do you know if a vaccine works? If everyone does not answer their census questionnaire, how can you count the number of people currently living in any area of the United States? How do you know if the medical procedure will benefit you? What about the weather? Should you buy the extended warranty? How do you begin to answer these and many many more questions? The answer is the subject of probability and statistics.
Every field has questions whose answers are found using statistical analysis tools. Every field uses statistics … and everyone needs to understand the concepts within probability and statistics to be successful in their daily personal lives.
HGS Probability and Statistics introduces students to the logic, visualization, descriptive methods, and inference using "pencil and paper" as well as computational tools one can use to begin to answer life's questions. Only Algebra II mathematics is required as a prerequisite for this non-calculus based class.
Join us fall 2023. Learn tools you can use in your college, professional, and personal life.
Probability and Statistics (P&S) is taught by Dr. Bruce Norton. The academic year block schedule class meets daily beginning at 10:00 am. with MTH 154 material covered in the fall semester and MTH 245 material covered in the spring semester.
P&S (MTH 154/245) is a non-calculus based course intended to introduce students with no prior knowledge of the subject to the academic discipline of quantative reasoning through the use of the statistical tools of data analysis, visualization, regression, and inference.
In order to take MTH 154/245 a student should have successfully completed Algebra II at the high school level. Familiarity with the use of a scientific level or higher (e.g., graphing) calculator to preform repetative basic math operations is also required. However, calculator pre-programmed statistics operations will not be used in the course.
Students should also have access to the interent outside of daily class time and a device (Windows, MAC OS, or Linux) capable of running software used in the course.
"Probability and Statistics incorporates both introductory non-calculus based statistics and quantitative reasoning. Thus, Probability and Statistics covers descriptive statistics, data visualization, experiment design, probability, probability distributions, estimation, hypothesis testing, correlation, and both nonlinear and linear regression. Statistical tools are used in problem solving and reasoning as well as model development and analysis. Large, real world data sets are examined using statistical software. Supporting topics, such as set theory and logic, are also covered with an introductory perspective."

Mathematics and music are closely related. And as teacher Michael Staff points out, their common ground could be partially connected with a Rubik’s Cube puzzle.
In a recent TedEd video lesson, “How to play a Rubik’s Cube like a piano,” Staff explains:
“If you were to cover your entire Rubik’s Cube with notes, such that every face of the solved cube is a harmonious chord, you could express the solution as a chord progression that gradually moves from discordance to harmony, and play the Rubik’s cube.”

Well, today is my birthday and Friday is Larry's. We will be 135. You can figure out our ages using algebra. X + Y = 135 and X + 1 = Y ! So, X + X + 1 = 135! So 2 X = 135 - 1! Lots of folks say they don't use algebra, but I always have. When I am trying to figure out an unknown, I often write out a formula. I liked algebra but never took very many high level math classes. I did take algebra in college. I also often use A squared + B squared = C squared! Guess I am a little weird!
I saw this picture on the Newton County History site. it was taken in 1910. The family lived on the Little Buffalo River! Looks like they are logging. I love the picture and wonder who it is! The site did not say.


I want to live in a world where it is not socially acceptable to say you are not a math person,” says Brittany Rhodes, founder of Black Girl MATHgic, a monthly subscription box designed to increase math confidence and decrease math anxiety in black girls.
With a degree in mathematics and years of tutoring experience, Rhodes is committed to bringing math to the forefront. Each month, girls will receive a box containing a math lesson with an activity booklet based around a theme and dedicated to math activities along with writing reflection.
Rhodes says, “We are conditioned to believe you have to be good at writing or math, not both.” Three to five math-related items will bring the theme further to life along with a profile of a black woman mathematician. The parent guide helps the adult in her life with tips and an answer explanation key.
Lessons are of a third-to-eighth grade level, when girls are building their math foundation in school. Rhodes says, “These are the ages where they disengage in math.” The box tackles multiplication, division, symmetry, unit rate, budgeting, subtraction, angles, fractions, decimals and more, all for $39.95.
“I chose to focus on math, especially,” she says. “I applaud the STEM effort, but I think the effort treats math as the appetizer when it should be the entree.” Rhodes wants to eventually take the subscription box international, and a Black Boy MATHgic box is also in the works.


The purpose of this seminar is to give you a good understanding of advanced quantitative risk measurement methods.
We start with an overall introduction to modern risk analysis and explain why risk measurement has become more important and challenging. We briefly review basic risk measures such as beta, duration, modified duration, convexity and standard deviation and discuss their limitations in a world with increasingly complex financial instruments.
We then give a thorough explanation of how “Value-at-Risk” and other measures of shortfall risk can be calculated for linear as well as non-linear exposures. We explain the use of delta-normal and delta-gamma-normal methods for the calculation of VaR for forwards, swaps and options, and we explain and demonstrate the use numerical techniques (including historical simulation and Monte Carlo simulation and principal components analysis) for calculating VaR of more complex instruments and portfolios.
Further, we explain how to back-test these “Value-at-Risk” models. As a particular case study, we look at the back-testing requirements of the Basel framework. We also take you a step further to show how the impact of estimation risks can be considered by using dynamic parametric VaR models and by correcting standard back-testing procedures.
Finally, we introduce Extreme Value Theory and explain and demonstrate its applications in finance. We present the two main approaches to estimating tail distributions: the “Block Maxima” and the “Peaks over Threshold” groups of models. We demonstrate how a “Generalized Pareto Distribution” can be fitted to real-life financial data (stock prices etc.), and we visualize results using graphical tools. We also explain and demonstrate how EVT can be used in financial risk management. We use extreme value theory to calculate conditional and non-conditional VaR, and we discuss the use of EVT in Stress Testing and in asset allocation.


Muhlenberg mathematics professors earn three-year NSF grant$323,916 award will bring students from across the country to campus for summer math research
Thursday, March 3, 2016 04:15 PM
Two faculty members in Muhlenberg College’s mathematics & computer science department have been awarded a three-year, $323,916 National Science Foundation (NSF) Directorate for Mathematical & Physical Sciences grant for their proposal, proposal, "Research Challenges of Identifying Integer Sequences Using the OEIS."
The grant was awarded to principal investigator Eugene Fiorini, Truman Koehler Professor of Mathematics, and co-principal investigator Byungchul Cha, associate professor of mathematics.
The funding will allow ten college students – selected from a national pool of applicants – to spend nine weeks on the Muhlenberg campus doing summer research and working on open-ended mathematics problems.
“The intellectual focus of the research concentrates on the important role sequences play in number theory, combinatorics, and discrete mathematics, as well as their contributions to other fields,” Fiorini said. “Our program aims to prepare students to become the next generation of mathematical scientists efficient in researching sequences and their applications through the OEIS database, the most successful of whom will have the capacity to look to the OEIS for inspiration.”
Students will work with mentors and do research projects associated with the On-Line Encyclopedia of Integer Sequences® (OEIS) and its role in stimulating new research.
In addition to Fiorini and Cha, three other mathematicians – Nate Shank from Moravian College, Joshua Harrington from Cedar Crest College and Kellen Myers from Farmingdale State College, SUNY – will serve as mentors.
After research projects are completed, students will disseminate their findings by writing and submitting papers to journals and giving presentations at regional and national conferences.
According to Fiorini, this project is the first Research Experience for Undergraduates (REU) devoted specifically to research associated with the OEIS. The impact of the OEIS as a resource tool for researchers can be seen in the large number of refereed journal articles and other publications that site it as a reference, over 3000 to date.

Elementary algebra, Abstract algebra Cheap Lucas Hernandez Jersey , Linear algebra and Universal algebra are the different parts of Algebra.
For example x + y = 9z is an arithmetic expression in which both side having an algebraic expression.
In the above equation x + y = 9z , here the equation consist of 3 terms x, y Cheap Koke Jersey , 9z which are separated by plus and equal to symbol. Here x , y and z are the variables with there respective coefficients 1, 1 and 9.
Let's take some college Algebra problems to understand it better: we need to write an equation for the following statement : The sum of father's age and one-fourth of the age of son is equal to 30.
In the above statement father's age + 录 son age = 30
let's take x as father's age and y as son's age. So the equation form as:
x + 14y = 30.
Now we are going to see one of the Algebra section comes with Inequalities. An inequality tells that two values are not equal. For example a 鈮?b shows that a is not equal to b. Slope formula plays an important role in graphing linear inequalities. So we need to know what slope formula means. Slope of a line describes the steepness Cheap Kevin Gameiro Jersey , incline or grade of the straight line.
Inequalities comes with various signs showing that the terms are unequal or not equal. As for solving inequalities we need to learn the symbols of inequalities like the symbol means greater than and the symbol 鈮?or 鈮?less than or equal to etc.
