st: FW: zinb help

Hi all,

I have asked this question before but got told off... but I am no closer to finding an answer... I know there is “nbfit”  to fit a  negative binomial distribution to a single variable by the method of maximum likelihood. Is there something similar to fit a zero inflated negative binomial distribution to a single variable? I found nbvargr which fits a poisson and a negbinomial dist to a variable but nothing on zero inflated distributions.

The only commands related to zero inflated models I found were zip and zinb...

I am sorry if it is still a very dumb question..

  Regards rajesh
