I know Richard McElreath is preparing the second edition of his book. How crazy will be to have an official PyMC3 version of it? I guess this could mean several things, two of them are:
Two printed versions one using R/Stan, one Python/PyMC3
Just one printed version (R/Stan) plus one official repository with the PyMC3 code
For this to happen we will need to have an agreement with the Author (and editorial), and we will need early access to the drafts. Porting the code should be easy given that we already have the first edition almost completely ported, and even if the second edition is completely new we could distribute chapters among several of us.
If this, somehow, generates profits, all money could be used to directly support PyMC3 development, I guess @fonnesbeck and others have a better picture of what is needed (if anything) in this regard.
I haven’t yet, I did not want to contact him without knowing if the idea has at least some support. I have only discussed this (very briefly) with @AustinRochford, he knows a guy that works (or used to work) with the author.
Update:
I emailed Richard yesterday and he replied to me promptly, basically he loved the idea to have the R and Python codes of the 2nd edition ready for release. He will keep us posted when there is a stable version of the 2nd edition (he said maybe a year from now).
