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 function that models the probability of success with respect ...
