fixef function

Extract fixed-effects estimates

Extract Fixed Effects methods

## S3 method for class 'glmmTMB'
fixef(object, ...)

Arguments

• object: any fitted model object from which fixed effects estimates can be extracted.
• ...: optional additional arguments. Currently none are used in any methods.

Returns

an object of class fixef.glmmTMB comprising a list of components (cond, zi, disp), each containing a (possibly zero-length) numeric vector of coefficients

Details

Extract fixed effects from a fitted glmmTMB model.

The print method for fixef.glmmTMB object only displays non-trivial components: in particular, the dispersion parameter estimate is not printed for models with a single (intercept) dispersion parameter (see examples)

Examples

data(sleepstudy, package = "lme4")
fm1 <- glmmTMB(Reaction ~ Days, sleepstudy)
(f1 <- fixef(fm1))
f1$cond
## show full coefficients, including empty z-i model and
## constant dispersion parameter
print(f1, print_trivials = TRUE)
