ISYE 6414 – Final Exam Questions and Answers 100% Correct 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-shape function that models the...

What is cooks distance used for? - correct answer It measures how much all of the values in the regression model change with the ith observation is removed. Basically its a test for outliers 
 
Rule of thumb: D denotes cooks distance, if D is > 4/n 
OR D > 1 or any large D then it may be an outlier and should be removed. 
 
If the normality assumption does not hold, we can pursue a transformation in the response variable. T/F - correct answer ...
