logLik.reStruct: Calculate reStruct Log-Likelihood

Description

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).

Usage

# S3 method for reStruct
logLik(object, conLin, ...)

Value

the log-likelihood, or restricted log-likelihood, of linear mixed-effects model represented by object and conLin, evaluated at coef{object}.

Arguments

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.
