extractSE | R Documentation |
This function extracts the standard errors (SE) of the fixed effects of
a mixed model fit with coxme
, glmer
, lmer
,
lmerModLmerTest
, and lmekin
and adds the appropriate labels.

additional arguments passed to the function. |
These extractor functions use vcov.coxme
, vcov.lmekin
,
vcov.mer
, and vcov.merMod
. Some of these functions are
called by modavg
and modavgShrink
, depending on the
class of the objects.
Returns the SE's of the fixed effects with the appropriate labels for each.
