FLXMRmultinom.RdModel driver for fitting mixtures of multinomial logit models.
FLXMRmultinom(formula = . ~ ., ...)A formula which is interpreted relative to the formula
specified in the call to flexmix using
update.formula. Default is to use the original
flexmix model
formula.
Additional arguments to be passed to nnet.default.
The M-step is performed using nnet.default.
Returns an object of class FLXMRmultinom inheriting from FLXMRglm.
Bettina Gruen and Friedrich Leisch. Identifiability of finite mixtures of multinomial logit models with varying and fixed effects. Journal of Classification, 25, 225–247. 2008.
To ensure identifiability repeated measurements are necessary. Sufficient conditions are given in Gruen and Leisch (2008).
