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)
REQUIRED ARGUMENTS:
reStruct
a
reStruct representing a random effects
structure.
OPTIONAL ARGUMENTS:
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.
