Stepwise model selection using zero-inflated negative binomial model personality?

[#1]

I am trying to evaluate models using delta-AIC, but I am not sure how to run a ZINB model and doing stepwise model selection to get those AIC

The Stepwise platform does not support responses with non-normal distributions. Use one of the model selection methods in the Generalized Regression platform in JMP Pro instead.
