Hi all, I am hoping someone can help with a problem I have. I want to do a zero-inflated negative binomial model on some count data. I have found how to get the model (using zicounts), and the test of each predictor on both the negative binomial and zero-inflated parts of the distribution. Can anyone tell me how I can also get an omnibus test of significance for the fit of the model? Stata I think gives a likelihood ratio chi-square test of the full versus null model for the zinb model. Is there a way to get this in R? Alternatively, is there a way I use the deviance, or maximum likelihood value to derive this?
