Research direction

Start by reviewing patsy’s existing categorical encoding support and the issue’s linked entropy example. Determine whether entropy-based encodings are already covered and, if not, define the expected encoding behavior and validation needed before implementation.

Written by the indexing model from the issue text.

Description

One of my favorite parts of patsy are the categorical encodings. That feature alone is worth using it. While playing with those options, I could not find encodings based on standard entropy calculations? Is that covered in there and I missed?

For an example of using entropy for categorical encodings, see this video: https://youtu.be/IPkRVpXtbdY?t=4m49s
