Plotting with ArviZ

[ahartikainen]

Hi, package looks great.

Due to the use of PyStan (maybe in future of CmdStanPy too) this package is already supported by ArviZ, but I think we should add some common regression plots.

Maybe we could work together to see what different kind of plots should be supported (what bayesplot does?)?

Thanks! :-)

Does ArviZ naturally support CmdStanPy?

That'd be great! What do you have in mind? Maybe something like listing the different plot kinds in Bayesplot/Shinystan and see which ones are already supported by ArviZ?

Yes, that sounds good.

We also have loo / updated diagnostics (rhat, ess) so these can also be used. Maybe we can create a custom wrapper, so log_likelihoods and posterior predictive are put in the correct locations in InferenceData (in ArviZ)
