| recalc.corStruct {nlme} | R Documentation |
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.
## S3 method for class 'corStruct': recalc(object, conLin, ...)
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. |
... |
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 correlated error terms.
