Extract fixed-effects estimates for a merModList

Usage

# S3 method for class 'merModList'
fixef(object, add.dropped = FALSE, ...)

Arguments

object: any fitted model object from which fixed effects estimates can be extracted.
add.dropped: for models with rank-deficient design matrix, reconstitute the full-length parameter vector by adding NA values in appropriate locations?
...: optional additional arguments. Currently none are used in any methods.

Value

a named, numeric vector of fixed-effects estimates.

Details

Extract the estimates of the fixed-effects parameters from a list of fitted merMod models. Takes the mean of the individual fixef objects for each of the component models in the merModList.

Examples

# \donttest{
sim_list <- replicate(n = 10,
        expr = sleepstudy[sample(row.names(sleepstudy), 180),],
        simplify=FALSE)
fml <- "Reaction ~ Days + (Days | Subject)"
mod <- lmerModList(fml, data = sim_list)
fixef(mod)
#> (Intercept)        Days 
#>   251.40510    10.46729 
# }
