You are conducting a multiple regression and in the process of screening you discover that you have a maximum Cook's distance score of .90. What should you do? a. Look at each of the variables for that influential case an make an executive decision regarding whether the case with the highest Cook's value is indeed an outlier or not. b. Reverse-code the variable. Save the Cook's values and view the data editor. Sort 'descending' so that you can find the case with the highest Cook's value (variable COO _1by default). Remove the influential case. 0 d. No treatment is required as the case is not influencing the model dramatically. Clear my choice
