ISYE6414 REGRESSION SUMMER MIDTERM 1 AND 2 EXAM / ISYE6414 MIDTERM 1 AND 2 REAL EXAM QUESTIONS AND 100% CORRECT ANSWERS/ GRADED A If the confidence interval for a regression coefficient contains the value zero, we interpret that the regression coefficient is definitely equal to zero. ---ANSWER-- False The larger the coefficient of determination or R-squared, the higher the variability explained by the simple linear regression model. ---ANSWER-- True The estimators of the error t...

Factor Based Models classification, clustering, regression. Implicitly assumed that we have a lot of factors in the final model 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 Classical variable selection approaches 1. Forward selection 2. Backwards elimination 3. Stepwise regression greedy algorithms Backward elimination...

We can assess the constant variance assumption in linear regression by plotting the residuals vs. fitted values. - correct answer True If one confidence interval in the pairwise comparison in ANOVA includes zero, we conclude that the two corresponding means are plausibly equal. - correct answer True The assumption of normality is not required in linear regression to make inference on the regression coefficients. - corr...
