Provide graphical evaluations of a set of classification models for the Loans data set. Do not include interest as a predictor. Make sure to develop the charts using the test data set. Construct and interpret separate profits charts for the CART model and the C5.0 model. (Extra credit: Find a way to construct a single profits chart comparing the two models.) Where is the peak profitability for each model? At what percentile does peak profitability occur? Which model is preferred, and why?
