It's not a proper fix, but our workaround is to edit the Makefile for
latex (and latexpdf) to
https://github.com/statsmodels/statsmodels/blob/master/scikits/statsmodels/docs/Makefile#L94
https://github.com/statsmodels/statsmodels/blob/master/scikits/statsmodels/docs/make.bat#L121
to call the script to replace the longtable arguments
https://github.com/statsmodels/statsmodels/blob/master/scikits/statsmodels/docs/fix_longtable.py
The workaround itself probably isn't optimal, and I'd be happy to hear
of a proper fix.
Cheers,
Skipper
