gnlsStruct: Generalized Nonlinear Least Squares Structure
Description
A generalized nonlinear least squares structure is a list of model
components representing different sets of parameters in the nonlinear
model. A gnlsStruct may contain corStruct and
varFunc objects. NULL arguments are not included in the
gnlsStruct list.
Usage
gnlsStruct(corStruct, varStruct)
Arguments
corStruct
an optional corStruct object, representing a
correlation structure. Default is NULL.
varStruct
an optional varFunc object, representing a
variance function structure. Default is NULL.
Value
a list of model variance-covariance components determining the
parameters to be estimated for the associated nonlinear model.
