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?
