Linear Mixed-Effects Structure
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 .

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.Value
a list of model components determining the parameters to be estimated
for the associated linear mixed-effects model.Author(s)
