lcmm, Jointlcmm or multlcmm objectsThe function computes the marginal predictions of the longitudinal
outcome(s) in their natural scale on the individual data used for the
estimation from lcmm, Jointlcmm or multlcmm objects.
fitY(x)an object inheriting from classes lcmm or multlcmm.
For lcmm and Jointlcmm objects, returns a matrix with
ng+1 columns containing the subject identifier and the ng class-specific
marginal predicted values.
For multlcmm objects, returns a matrix with ng+2 columns containing
the subject identifier, the outcome indicator and the ng class-specific
predicted values.
