From: Vishal Bali on
I am using National Survey on Drug Use and Health (NSDUH) for my analysis. I
have used Proc Genmod and Repeated Subject statement to obtain robust standard
errors in Poisson and negative binomial regression

It would be really helpful if somebody can please tell me about the STATEMENT
AND SYNTAX to be used to obtain robust standard errors in Zero inflated
Poisson and Zero inflated negative binomial regression.

Thanks,
