Variance Weights for lmeStruct Object

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:

varWeights(object) 

REQUIRED ARGUMENTS:

object
an object inheriting from class lmeStruct, representing a list of linear mixed-effects model components, such as reStruct, corStruct, and varFunc objects.

VALUE:

if object includes a varStruct component, a vector with the corresponding variance weights; else, or a vector of ones.
