lmeStruct: Linear Mixed-Effects Structure

Description

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

Usage

lmeStruct(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 linear mixed-effects model.
