Comment:

 Thanks for reporting.

 mstats takes in some cases the docstrings from stats, and I assume I
 forgot to check that when I added ddof to stats but not to mstats.

 ddof should have an effect on the reported pvalue, since it changes the
 degrees of freedom for the chisquare distribution. ddof does not affect
 the test statistic itself.
 Do you have a case where this is not correct?

 I think ddof can be added to the mstats version in the same way as in
 stats.
