I just replied for most of this.

My test run in the middle of the weekend (before I gave up), had about
4 or 5 test failures in the new _logpdf _logcdf methods.

Third and forth moments (skew, kurtosis) might still return about 5%
incorrect numbers, which I accept since it was written at a different
time. Same with many generic methods in stats.distributions that I
fixed two and a half years ago and which seems to never have worked
from what I inferred from the history.

denominator: functions/methods that return numbers
5-10% is just a guess, I never tried to measure it, maybe it's only
3%, but each one requires an afternoon to hunt down the reference and
the correct formula.
