After you open a data file, the Model Setup dialog automatically appears. This is the control center housing all model setup and refinement options in one convenient location.
To run an analysis all you have to do is:
- Select your target variable, in this case "BAD"
- Specify that this is a "Classification" problem
- State that BAD has two levels starting with 0
You don't have to select predictors if it is OK for CART to use all available columns. In this case we didn't want CART to use ID or similar information so we opted to list predictors explicitly. Note the running count kept of the number of predictors selected so far -- 15.
Eventually you will want to learn how to take advantage of the controls and options available on each of the Model Setup tabs. The good news is that all the options are set to intelligent defaults so you can get started without worrying about them.
