VarCorr {lme4} | R Documentation |
This function calculates the estimated variances, standard
deviations, and correlations between the random-effects terms in a
linear mixed-effects model, of class lme
, or a generalized
linear mixed-effects model, of class glmm
. When appropriate,
the within-group error variance and standard deviation are also
calculated.
