[R-sig-ME] GoodnessOfFit-and-PseudoR²computingFor-glmmTMB-models

[C. AMAL D. GLELE]

Hi, dear all
Please, your help for the following problem:
when I fit a mixed model using glmmTMB (poisson family or others), how do I:
1) check, if the model fits well my data (goodness of fit)?
2) check if my model is overdisperced or not (by using sigma(model)?)
3) compute an pseudo R² to see the percentage of the variability of my
response which is explained by my model?
In advance, thanks for your answers.
Regards,
