Which variable should you remove? Intercept profit Appr1 Appr2 Appr3 none of the above Question 37 Remove that variable and RE-RUN. Using this second regression (removing the first variable), what is your expected profit for the following scenario: Appr1: 20 Appr2: 1 Appr3: 40 Give answer to 2 decimal places (the final answer is between 20-200). Question 38 What is your r2 (to 3 decimal places)? Question 39 Which variable should you remove of the remaining ones? Intercept profit Appr 1 Appr2 Appr3 none of the above/keep the remaining variables Question 40 If your variance tends to increase with an increase in the independent (and/or dependent) variable, this is called: multicollinearity heterocollinearity homoskedesticity heteroskedesticity
