Log-Likelihood of a glsStruct Object

Usage

logLik(object, Pars, conLin)

Arguments

object an object inheriting from class gls, representing a generalized least squares fitted linear model.
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").

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.

Value

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