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). |

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 non-zero 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. |
