Issue description

I am the original author of the GLM in PyMC3: Out-Of-Sample Predictions notebook. @drbenvincent did a fantastic job improving it 🚀 ...but it seems the old (mine initial) version is in the master branch. I believe it was modified in #376 . It would be great to bring Ben's updated version back!

Expected output

Lates corrected version which was available before.

Proposed solution

Maybe revert #376 ? or simply fix this notebook? My concern is that this could have happened to other notebooks ¯\(ツ)/¯

Thanks for spotting this!

I think we should remove the NB as it's using the glm submodule.

@drbenvincent did a whole re-write of this notebook, it was great! the problem is that in the PR referenced abve for some reason the new version was replaced by the old one. See the notebook diff in #376 ;)

So I guess I need to fix this and bring the updated notebook back to life.

Time wise, could get to that summer point in the festive season when taking a break from my family. If there's urgency then happy if someone else wants to resolve it.
