logLik.gnls: Log-Likelihood of a gnls Object

Description

Returns the log-likelihood value of the nonlinear model represented by object evaluated at the estimated coefficients.

Usage

# S3 method for gnls
logLik(object, REML, …)

Arguments

object

an object inheriting from class "gnls", representing a generalized nonlinear least squares fitted model.

REML

an logical value for consistency with logLik,gls, but only FALSE is accepted..

…

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

Value

the log-likelihood of the linear model represented by object evaluated at the estimated coefficients.
