recalc.varFunc: Recalculate for varFunc Object

Description

This method function pre-multiples the "Xy" component of conLin by a diagonal matrix with diagonal elements given by the weights corresponding to the variance structure represented by objecte and adds the log-likelihood contribution of object, given by logLik(object), to the "logLik" component of conLin.

Usage

# S3 method for varFunc
recalc(object, conLin, ...)

Value

the recalculated condensed linear model object.

Arguments

object

an object inheriting from class "varFunc", representing a variance function structure.

conLin

a condensed linear model object, consisting of a list with components "Xy", corresponding to a regression matrix (X) combined with a response vector (y), and "logLik", corresponding to the log-likelihood of the underlying model.

...

some methods for this generic require additional arguments. None are used in this method.
