logLik.gnls {nlme} | R Documentation |
Returns the log-likelihood value of the nonlinear model represented by
object
evaluated at the estimated coefficients.
## S3 method for class 'gnls': logLik(object, REML, ...)
object |
an object inheriting from class gnls , representing
a generalized nonlinear least squares fitted 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 . |
... |
some methods for this generic require additional arguments. None are used in this method. |
the log-likelihood of the linear model represented by
object
evaluated at the estimated coefficients.
