FLXfit(model, concomitant, control, postunscaled = NULL, groups,
       weights)

`model`	List of `FLXM` objects.
`concomitant`	Object of class `FLXP`.
`control`	Object of class `FLXcontrol`.
`weights`	A numeric vector of weights to be used in the fitting process.
`postunscaled`	Initial a-posteriori probabilities of the observations at the start of the EM algorithm.
`groups`	List with components `group` which is a factor with optional grouping of observations and `groupfirst` which is a logical vector for the first observation of each group.
