Hello, I am running my first zero inflated negative binomial regression, and of course, having fun : ). I would like to get predicted probabilities for the logistic part of the model to see who is likely to go from a '0' to a value of 1 or more. I didn't see a way to save them, but can I just calculate it just like I'd do for a logistic regression? Thanks for any advice. 


I think so since no random effect enters into this part of the model. I assume you are talking about the inflation equation (being able to only observe zero or not).

Yep, thanks.

Hello again . . . using only the logistic estimates doesn't seem to be working, and I'm guessing it's because I'm not using information from the other model. Is there a way to save predicted probabilities in a file? I've looked through the manual and tried a few things, but have not been successful. Thanks. 


Note that the logistic part predicts the inflation (the class of people who can only have zero), so not the probability of observing a zero. The nonzero class people also have a probability of zero. I don't think we save those probabilities. 


Actually, we provide plots for both the count and the binary (inflated) part if you have the inflated part mentioned in the SERIES option. Which means that you can save those values.
