, or a nonlinear
mixed-effects model, of class "nlme"
. The within-group error
variance and standard deviation are also calculated.VarCorr(x, sigma = 1, …)
# S3 method for lme

.Variance
and StdDev
, give, respectively, the variance
and the standard deviations. If there are correlation components in
the random effects model, the third column, named Corr
,
and the remaining unnamed columns give the estimated correlations
among random effects within the same level of grouping. The
within-group error variance and standard deviation are included as
the last row in the matrix.lme
