[R] Zero inflated count models
Can someone show me how to specify zero inflated poisson and zero inflated negative poisson models in R? I would like to replicate the example given in Long (1997: Regression Models for Categorical and Limited Dependent Variables) in Chapter 8.5 (pp. 242-247).

[R] Zero inflated count models (2)
In my previous mail, meant to say negative binomial regression (not negative poisson), of course.

TIA Dirk Dirk, I believe this can be done with Jim Lindsey's fmr function in the gnlm package. The help page has an example of both ZIP and ZINB model fits. The gnlm package can be downloaded from http://alpha.luc.ac.be/~jlindsey/rcode.html -sundar __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
