logLik.glsStruct: Log-Likelihood of a glsStruct Object

Description

Pars is used to update the coefficients of the model components of object and the individual (restricted) log-likelihood contributions of each component are added together. The type of log-likelihood (restricted or not) is determined by the settings attribute of object.

Usage

# S3 method for glsStruct
logLik(object, Pars, conLin, ...)

Value

the (restricted) log-likelihood for the linear model described by

object, evaluated at Pars.

Arguments

object

an object inheriting from class "glsStruct", representing a list of linear model components, such as corStruct and "varFunc" objects.

Pars

the parameter values at which the (restricted) log-likelihood is to be evaluated.

conLin

an optional 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 linear model. Defaults to attr(object, "conLin").

...

some methods for this generic require additional arguments. None are used in this method.
