Description
Extract the estimated variances, standard
deviations, and correlations of the random-effects terms in a
linear mixed-effects model, of class lme, or a generalized
linear mixed-effects model. When appropriate,
the within-group error variance and standard deviation are also
calculated.
Usage
VarCorr(x, ...)
Arguments
x
a fitted model object, usually an object inheriting from
class lmer.
