ISYE 6501 FINAL EXAM WITH COMPLETE SOLUTION 2022/2023 1. Factor Based Models: classification, clustering, regression. Implicitly assumed that we have a lot of factors in the final model 2. Why limit number of factors in a model? 2 reasons: overfitting: when # of factors is close to or larger than # of data points. Model may fit too closely to random effects simplicity: simple models are usually better 3. Classical variable selection approaches: 1. Forward selection 2. Backwards eli...

Econometrics Midterm & Final Exam Questions and answers Econometrics -Answer-The science of testing economic theories. Also it works as a set of tools used for forecasting future values of economic variables as well as being the process of fitting mathematical economic models to real world data. Econometrics uses historical data to make numerical, or quantitative, policy recommendations in government and business. Y-bar -Answer-The sampling average. It is an unbiased estimator for miuY, ...

OMSA Midterm Exam Questions With Complete Solutions Latest Updated 2023/2024. DOE - Answer- systematic method to determine the relationship between factors affecting a process and the output of that process. must make sure either: 1) 2 data sets have same mix 2) break down data into smaller tests that test all factors, not just one. forward selection - Answer- go step by step either narrowing or building a model -- begin with no factors. only allow new factors with p-value 0.1 or lower an...

Bernoulli Trial - An experiment in which there are exactly two possible outcomes Binomial distribution - A random variable X represents the number of successes observed from the n Bernoulli trials Binomial Parameters - n = number of trials p = probability of success q = 1-p Binomial probability function (f(x)) - E[X] binomial function - E[x] = np var(x) binomial function - var(x) = npq MGF binomial function - Additive property of binomial function - Sum of independent binomially dist...
