| recalc.varFunc {nlme} | R Documentation |
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, ...)

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.
