| varWeights.glsStruct {nlme} | R Documentation |
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.
## S3 method for class 'glsStruct': varWeights(object)
object |
an object inheriting from class glsStruct,
representing a list of linear model components, such as
corStruct and varFunc objects. |
if object includes a varStruct component, a vector with
the corresponding variance weights; else, or a vector of ones.
