logLik.gnlsStruct {nlme} | R Documentation |
Pars
is used to update the coefficients of the model components
of object
and the individual log-likelihood
contributions of each component are added together.
## S3 method for class 'gnlsStruct': logLik(object, Pars, conLin, ...)
object |
an object inheriting from class gnlsStruct ,
representing a list of model components, such as
corStruct and varFunc objects, and attributes
specifying the underlying nonlinear model and the response variable. |
Pars |
the parameter values at which the 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 nonlinear model. Defaults to attr(object,
"conLin") . |
... |
some methods for this generic require additional arguments. None are used in this method. |
the log-likelihood for the linear model described by object
,
evaluated at Pars
