Calculates 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). The settings attribute of
object determines whether the log-likelihood, or the restricted
log-likelihood, is to be calculated. The computational methods are
described in Bates and Pinheiro (1998).
# S3 method for reStruct
logLik(object, conLin, ...)the log-likelihood, or restricted log-likelihood, of linear
mixed-effects model represented by object and conLin,
evaluated at coef{object}.
an object inheriting from class "reStruct",
representing a random effects structure and consisting of a list of
pdMat objects.
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.
