Pip dependencies

[emanuelvianna]

I've noticed that field install_requires was not filled at setup.py.

Hence, the dependencies are not installed through pip command.

I've installed the dependencies through apt-get build-dep python-statsmodels that could not be last one (pip can be more updated).

Could statsmodel do it for us?

Very best regards,
Emanuel

So far we have avoided letting pip resolve the dependencies on purpose due to pip's recursive upgrade behavior IIRC.

@emanuelvianna see gh-1897 for more details. This is a duplicate of that and several other issues, so closing.
