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 could 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,
