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...

ISYE 6414 Regression Modules 1-2 (2023/2024) Already Passed Assuming that the data are normally distributed, under the simple linear model, the estimated variance has the following sampling distribution: Chi-squared with n-2 degrees of freedom. The fitted values are defined as? The regression line with parameters replaced with the estimated regression coefficients. The estimators fo the linear regression model are derived by? Minimizing the sum of squared differences between the observed and ...
