FLXMRmultinom: FlexMix Interface to Multiomial Logit Models
Description
Model driver for fitting mixtures of multinomial logit models.Usage
FLXMRmultinom(formula = . ~ ., ...)

Additional arguments to be passed to nnet.default.
Value
- Returns an object of class
FLXMRmultinom.
Warning
To ensure identifiability repeated measurements are
necessary. Sufficient conditions are given in Gruen and Leisch (2008).Details
