ISYE 6414 Midterm Prep Questions and Answers Graded A+ We can assess the constant variance assumption in linear regression by plotting the residuals vs. fitted values. True If one confidence interval in the pairwise comparison in ANOVA includes zero, we conclude that the two corresponding means are plausibly equal. True The assumption of normality is not required in linear regression to make inference on the regression coefficients. False (Explanation: is required) We cannot estimate a multi...

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 probability of success with respect to the predict...
