I have settled on a Negative Binomial Model in which I would like to also get an estimate for the overdispersion parameter. While all the other estimates appear and are estimated, I can see the overdis...

Hi All, I am trying to estimate a Random Coefficient Model in a Negative Binomial framework and the variance structure looks to be a little wonky. I have a few questions and am hoping for a little guidance to run this model. 1. After switching to Neg. Binomial Regression, designating Y and offset. S...
