Visualizing multiple explanatory variables

Plotting has similar issues as with the linear regression case: it quickly becomes difficult to include more numeric variables in the plot. Here you'll look at the case of two numeric explanatory variables, and the solution is basically the same as before: use color to denote the response.

Here there are only two possible values of response (zero and one), both in the actual dataset and the predicted dataset.

churn and prediction_data are available.
