After running a mixed-effects Conway-Maxwell Poisson model using glmmTMB, I've printed the results using sjPlot's tab_model() but I don't know what R2 calculation is being used.
Is it Nakagawa's R2 since it is a mixed-effects model?
Also, I've come across some difficulties trying to find a way of computing r2 for Conway-Maxwell Poisson (with no hierarchical structure)...is there a straightforward way of doing this?
