Log-Likelihood of a gls Object
Usage
logLik(object, REML)
Arguments
object
|
an object inheriting from class gls , representing
a generalized least squares fitted linear model.
|
REML
|
an optional logical value. If TRUE the restricted
log-likelihood is returned, else, if FALSE , the log-likelihood
is returned. Defaults to FALSE .
|
Description
If REML=FALSE
, returns the log-likelihood value of the linear
model represented by object
evaluated at the estimated
coefficients; else, the restricted log-likelihood evaluated at the
estimated coefficients is returned.Value
the (restricted) log-likelihood of the linear model represented by
object
evaluated at the estimated coefficients.Author(s)
