Use the churn data set, given at the book series website, for the following exercises. Use the Churn_Training_File. Filter out all variables except the following: VMail Plan, Intl Plan, CustServ Calls, and Churn. Set CustServ Calls to be ordinal. Allow the three predictors to be in either antecedent or consequent, but do not allow Churn to be in the antecedent.

Compare the results from Exercise 13 with the results from the EDA and decision tree analysis in Chapters 3 and 6. Discuss similarities and differences. Which analysis format do you prefer? Do you find a confluence of results?
