(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).

representing a random effects structure and consisting of a list of
pdMat objects.

"logLik", corresponding to the log-likelihood of the
underlying model.
