logLik.reStruct {nlme} | R Documentation |
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 class 'reStruct': logLik(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. |
... |
some methods for this generic require additional arguments. None are used in this method. |
the log-likelihood, or restricted log-likelihood, of linear
mixed-effects model represented by object
and conLin
,
evaluated at coef{object}
.
