| glsStruct {nlme} | R Documentation |
A generalized least squares structure is a list of model components
representing different sets of parameters in the linear
model. A glsStruct may contain corStruct and
varFunc objects. NULL arguments are not included in the
glsStruct list.
glsStruct(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 linear model.
