nlmeStruct {nlme}

Nonlinear Mixed-Effects Structure

Description

A nonlinear mixed-effects structure is a list of model components representing different sets of parameters in the nonlinear mixed-effects model. An nlmeStruct list must contain at least a reStruct object, but may also contain corStruct and varFunc objects. NULL arguments are not included in the nlmeStruct list.

Usage

nlmeStruct(reStruct, corStruct, varStruct)

Arguments

reStruct

a reStruct representing a random effects structure.

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 components determining the parameters to be estimated for the associated nonlinear mixed-effects model.
