lmeStruct {nlme} | R Documentation |
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.
lmeStruct(reStruct, corStruct, varStruct)
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 . |
a list of model components determining the parameters to be estimated for the associated linear mixed-effects model.
