Recalculate for varFunc Object
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 class 'varFunc' recalc(object, conLin, ...)

some methods for this generic require additional arguments. None are used in this method. |
the recalculated condensed linear model object.
This method function is only used inside model fitting functions,
such as lme and gls, that allow heteroscedastic error
terms.
