For GLMMs of class glmerMod
, glmmTMB
or MixMod
,
the absolute unconditional deviance is returned (see 'Details' in
?lme4::merMod-class
), i.e. minus twice the log-likelihood. To get
the relative conditional deviance (relative to a saturated model,
conditioned on the conditional modes of random effects), use deviance()
.
The value returned get_deviance()
usually equals the deviance-value
from the summary()
.
