recalc.reStruct {nlme} | R Documentation |
The log-likelihood, or restricted log-likelihood, of the
Gaussian linear mixed-effects model represented by object
and
conLin
(assuming spherical within-group covariance structure),
evaluated at coef(object)
is calculated and added to the
logLik
component of conLin
. The settings
attribute of object
determines whether the log-likelihood, or
the restricted log-likelihood, is to be calculated. The computational
methods for the (restricted) log-likelihood calculations are described
in Bates and Pinheiro (1998).
recalc(object, conLin)
object |
an object inheriting from class reStruct ,
representing a random effects structure and consisting of a list of
pdMat objects. |
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. |
the condensed linear model with its logLik
component updated.
