Variance Weights for glsStruct Object

Usage

varWeights(object)

Arguments

object an object inheriting from class glsStruct, representing a list of linear model components, such as corStruct and varFunc objects.

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 model is returned.

Value

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