ISYE 6414 Final Exam Review 2022 with complete solution

Least Square Elimination (LSE) cannot be applied to GLM models. - ANS False - it is applicable but does not use data distribution information fully. In multiple linear regression with idd and equal variance, the least squares estimation of regression coefficients are always unbiased. - ANS True - the least squares estimates are BLUE (Best Linear Unbiased Estimates) in multiple linear regression. Maximum Likelihood Estimation is not applicable for simple linear regression and multiple l...

ISYE 6414 Final Exam; Questions and Answers 100% Verified True - The relationship that links the predictors is highly non-linear. Answer-In Logistic Regression, the relationship between the probability of success and the predicting variables is non-linear. False - In logistic regression, there are no error terms. Answer-In Logistic Regression, the error terms follow a normal distribution. True - the logit function is also known as the log-odds function, which is the ln(P/1-p). Ans...

ISYE 6414 Final Exam; Questions and Answers 100% Verified Logistic regression is different from standard linear regression in that: Answer-It does not have an error term; The response variable is not normally distributed; It models probability of a response and not the expectation of the response Logistic regression models Answer-The probability of a success given a set of predicting variables In logistic regression Answer-The estimation of the regression coefficients is based on m...

In a greenhouse experiment with several predictors, the response variable is the number of seeds that germinate out of 60 that are planted with different treatment combinations. A Poisson regression model is most appropriate for modeling this data - False - poisson regression models rate or count data. The R-squared and adjusted R-squared are not appropriate model comparisons for non linear regression but are for linear regression models. - TRUE - The underlying assumption of R-squared cal...
