ISYE 6414 Final Exam; Questions and Answers 100% Verified Logistic Regression Answer-Commonly used for modeling binary response data. The response variable is a binary variable, and thus, not normally distributed. In logistic regression, we model the probability of a success, not the response variable. In this model, we do not have an error term g-function Answer-We link the probability of success to the predicting variables using the g link function. The g function is the s-shape f...

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...

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 Review Questions and Answers 100% Pass Least Square Elimination (LSE) cannot be applied to GLM models. 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.
