model fit (r2) for glmmTMB I am having a really hard time finding certain summary statistics when running a beta generalized linear mixed model using the glmmTMB function in R. I would like to report the model fit (r2) for both the full model(random + fixed effects) and just the fixed effects as well as the x2 statistic for each fixed effect.

The marginal (no random effects) and conditional (with random effects) can be estimated by predicting the responses for the fixed-only (marginal) and full (conditional) models, correlating to the response data points, and squaring.
