`check_zeroinflation()` for `lme4::glmer.nb()`model #381

Closed maxsitt closed 2 years ago

maxsitt commented 2 years ago

Currently the function check_zeroinflation() is not working for a mixed model with negative binomial distribution, fitted with lme4::glmer.nb(). Error message: Error: $ operator not defined for this S4 class

glmer.nb() is not mentioned as supported model class in the function reference, so this might be a already known problem. I would be interested in the reason why it is not possible to include glmer.nb() as model class for check_zeroinflation(). Is there maybe a simple workaround to still check for zero-inflation in glmer.nb() models with one of the easystats tools?

Thank you for your answer!
