Arguments
object
an object inheriting from class lmeStruct
,
representing a list of linear mixed-effects model components, such as
reStruct
, corStruct
, and varFunc
objects.
data
a data frame in which to evaluate the variables defined in
formula(object)
.
groups
a data frame with the grouping factors corresponding to
the lme model associated with object
as columns, sorted from
innermost to outermost grouping level.
conLin
an optional condensed linear model object, consisting of
a list with components "Xy"
, corresponding to a regression
matrix (X
) combined with a response vector (y
), and
"logLik"
, corresponding t
control
an optional list with control parameters for the
initialization and optimization algorithms used in
lme
. Defaults to list(niterEM=20, gradHess=TRUE)
,
implying that 20 EM iterations are to be used in the derivation of
...
