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 gnlsStruct
logLik(object, Pars, conLin, ...)the log-likelihood for the linear model described by object,
evaluated at Pars.
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.
the parameter values at which the log-likelihood is to be evaluated.
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.
