IRR

[AY_MANSA]

Hi everyone

I am trying to get the incience risk ratio (irr) for each of my independent variables while also using the zero inflated negative binomial regression. How can i do this as the output for ZINB does not give the irr.

Thanks

@AY_MANSA welcome to the SAS forums.

Please note that I've merged your questions into one post and moved it into the Statistical Procedures forum. 

Would it be possible for you to generate a sample of your model or at least show your code for the proc.

I would recommend with working with a dataset out of the SASHELP library or from the documentation examples.
