This method function pre-multiples the
Xy component of
conLin
by the transpose square-root factor(s) of the
correlation matrix (matrices) associated with
object and adds
the log-likelihood contribution of
object, given by
logLik(object)
, to the
logLik component of
conLin
.
USAGE:
recalc(object, conLin)
REQUIRED ARGUMENTS:
object
an object inheriting from class
corStruct,
representing a correlation 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.
VALUE:
the recalculated condensed linear model object.
NOTE: This method function is only used inside model fitting
functions, such as
lme and
gls, that allow correlated error
terms.
