## Smarter Regression

Here's the add-in.
Remember that the first row **must ** be column names, and the
second row **must** contain the set of column types. Each column should
contain exactly one of these, spelled exactly as below (including the
capital letter):

- Ignore (don't use this column);
- Numeric (a numeric predictor);
- Categorical (a categorical predictor);
- Cat (an alternative label for a categorical predictor);
- Response (a numeric response);
- RespCat (a (two-level) categorical response, for logistic regression).
