I was going through several chapters of Agresti's Categorical Data Analysis book.
It's a lot of work doing many or all of the examples.
But it's very useful to see where statsmodels does not cover a part or where it's cumbersome to do the equivalent to something that is easy in R or Stata.
I like to open issues in the hope that eventually we get around to adding to and improving statsmodels.
We have over 2000 open issues.
One nice thing about books or websites with "R and Python" is that we have the direct comparison without doing a long search.
