ISYE 6414 – Final Exam Questions and answers, 100% Accurate. Rated A+ Logistic Regression - -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 - -We link the probability of success to the predicting variables using the g link function. The g function is the s-sh...
