gnlsStruct {nlme} | R Documentation |
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.
gnlsStruct(corStruct, varStruct)
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 . |
a list of model variance-covariance components determining the parameters to be estimated for the associated nonlinear model.
