Is there such a package that provides for zero-inflated negative binomial mixed-effects model estimation in R?

By that I mean:

  • Zero-inflation where you can specify the binomial model for zero inflation, like in function zeroinfl in package pscl:

    zeroinfl(y~X|Z, dist = "negbin")
    where Z is the formula for the zero inflation model;

  • Negative binomial distribution for the count part of the model;

  • Random effects specified similar to function lmer of package lme4.

I understand glmmADMB can do all that, except the formula for zero inflation cannot be specified (it is just an intercept, i.e. Z is just 1). But are there any other packages that can do it all?

I will be very thankful for your help!

I'm looking for the same thing. I think glmmADMB is what I want, but I can't get it running. –  gmacfarlane Dec 7 '12 at 20:41
    
I'm wondering whether or not the ZIM or aod packages can do what you want to do? –  Graeme Walsh Jun 26 '13 at 10:28

The pscl package provides for a zero inflated Poisson model. I don't think that it can do a negative binomial model, but it might be a place to start. The linked JSS article also discusses related packages, which may lead you to what you're looking for.
