no data cleaning for statsmodels.genmod.families.varfuncs.NegativeBinomial()

[t0mpr1c3]

p = self.clean(mu)
return mu + self.alpha_mu*2

nothing is done with the object p

If the data cleaning is necessary I would have thought the code should be

mu = self.clean(mu)
return mu + self.alpha_mu*2

Thanks for the report, clearly a typo.

a warning:
genmod.NegativeBinomial does not have any unittests so far.
discrete.NegativeBinomial has unittests

GLM Negative Binomial has unit tests

my mistake: I don't know why I didn't see the tests, when I checked
