Modeling Zero-Inflated Regression Models Using SAS (Procedure IML)



Help!!!

I understand the theory behind zero inflated regression models. I am
having difficulty writing a program using proc iml and if i can see a
demonstration of this I am sure I can do the rest to manipulate the
zero inflated regression model I am trying to fit. A program using the

SAS proc iml for a demonstration of the Zero Inflated Poisson
regression model or the Zero Inflated Negative Binomial regression
model would help may be with two covariates for the mean function and 2

covariates for the inflation function.


Thanks in advance
