my numbers don't match up with Stata while trying out different models

    def _ll_nbin(self, params, alpha, Q=0):
        endog = self.endog
        mu = np.exp(, params))

I'm running several different models in the interpreter and still need to get a nice script to replicate and test case.

The test case that I'm working on is to verify cluster robust standard errors, PR will follow soon.


duplicate, I opened a new issues #1611
fixed in #1612
