Description
If object includes a varStruct component, the inverse of
the standard deviations of the variance function structure represented
by the corresponding varFunc object are returned; else, a
vector of ones of length equal to the number of observations in the
data frame used to fit the associated linear mixed-effects model is
returned.
Usage
