summary for glmmTMB fits
a fitted glmmTMB object
use the sandwich estimator for the variance-covariance matrix? (this only works for ML fits, but not for REML fits)
denominator degrees-of-freedom calculation. Default "asymptotic" gives standard Z-statistics
(i.e., 'infinite' denominator df); "kenward-roger" uses the Kenward-Roger approximation, which will
be ignored for non-REML fits and is entirely untested for GLMMs (see dof_KR);
"satterthwaite" uses a Satterthwaite approximation
grouping factor for the sandwich estimator, only used if sandwich==TRUE.
