add to api, and docs
mixed_linear.rst is copy paste from module docstring and release notes. I didn't read the details
REF: rename module mixed_linear_model, add to api
DOC: add mixedlm to documentation, separate rst
Coverage increased (+0.0%) when pulling a9a7d9f on josef-pkt:lme_api_docs into 252cb5b on statsmodels:master.
This renames the module as discussed in #1695
The rst documentation is just cut and paste of what you have written in the release notes and module docstring.
You might want to check this, and update the example notebooks on the Wiki
I will try to go over some examples and the documentation during vacation
