Hierachical Hurdle Negative Binomial

specification

#1

Hello. I am performing hierachical hurdle negative binomial using #brms package. I wanted to know how to obtain the two parts of the results/coefficients (logit and count) after fitting the model. If I use either summary () or fitted () the results are combined.

Hello!

Instead of modelling, you should add the ‘brms’ tag to your post. Without it, Paul ( the package manager and creator) will not see your post!

Thanks. I just did.

The coefficients appear both in the output if you modeled both parts. By default, just the count part will have coefficients, while the hurdle probability is assumed constant over observations. If you want to learn how to model both parts, see vignette("brms_distributional")
