[R-sig-ME] Extracting standardized residuals from a gamma(log) glmmTMB

[Aoibheann Gaughran]

Hi all,

I have run a glmmTMB with (family="Gamma",link="log") and now want to
validate the model, but am unable to extract the standardised residuals
with sresid <- resid(mod1tmb, "pearson").  It produces the following error
message:

Error in residuals.glmmTMB(mod1tmb, "pearson") :
variance function undefined for family ‘Gamma’; cannot compute Pearson residuals


Would anyone be able to assist me with this?

Many thanks,
