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

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.
