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 class 'glsStruct'
logLik(object, Pars, conLin, ...)

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.

Value

the (restricted) log-likelihood for the linear model described by object, evaluated at Pars.
