[FMM] Finite Mixture Models - Stata
www.stata.comfmm uses the multinomial logistic distribution to model the probabilities for the latent classes. The probability for the ith latent class is given by ˇ i = exp(i) P g j=1 exp(j) where i is the linear prediction for the ith latent class. By default, the first latent class is the base level so that 1 …
