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.
# S3 method for varFunc
recalc(object, conLin, ...)the recalculated condensed linear model object.
an object inheriting from class "varFunc",
representing a variance function structure.
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.
