Checking for model fit from generalized linear mixed models (GLMM) can be challenging. The DHARMa package helps with this by giving simulated residuals but doesn't work with all model types. I show how to use tools in DHARMa to extend it for use with unsupported models fit with glmmTMB() and zeroinfl().

I currently work as a consulting statistician, advising natural and social science researchers on statistics, statistical programming, and study design. I create and teach R workshops for applied science graduate students who are just getting started in R, where my goal is to make their transition to a programming language as smooth as possible. See my workshop materials at my website.
