`summary()` fails with the new pandas release

[bersavosh]

Pandas 1.0 has been released and the keyword joint_axis is now removed from concat().

This causes pymc3's summary() to fail with the following error:

~/anaconda3/lib/python3.6/site-packages/pymc3/stats.py in summary(trace, varnames, transform, stat_funcs, extend, include_transformed, alpha, start, batches)
    980         rhat_pd = dict2pd(rhat, 'Rhat')
    981         return pd.concat([dforg, n_eff_pd, rhat_pd],
--> 982                          axis=1, join_axes=[dforg.index])
    983 
    984 

TypeError: concat() got an unexpected keyword argument 'join_axes'

Could you please update your pymc3 install to the newest version - this is not a problem in the newer versions as we are using arviz for diagnostic and plotting.

Oh sorry, did not notice that. Will do, thanks for the reply.
