fitted(object, levels, nlmeFit, conLin)
nlmeStruct,
representing a list of mixed-effects model components, such as
reStruct,
corStruct, and
varFunc objects, plus
attributes specifying the underlying nonlinear model and the
response variable.
object. Level
values increase from outermost to innermost grouping, with
level zero corresponding to the population fitted values. Defaults to
the highest or innermost level of grouping.
"Xy", corresponding to a regression
matrix (
X) combined with a response vector (
y), and
"logLik", corresponding to the log-likelihood of the
underlying nlme model. Defaults to
attr(object, "conLin").
level,
the returned value is a vector with the fitted values at the desired
level; else, when multiple grouping levels are specified in
level
, the returned object is a matrix with
columns given by the fitted values at different levels.
NOTE: This method function is generally only used inside
nlme and
fitted.nlme
.
