In cmollica/PLMIX: Bayesian Analysis of Finite Mixture of Plackett-Luce Models

Description

The function Estep updates the posterior component membership probabilities in the EM algorithm for MAP estimation of a Bayesian mixture of Plackett-Luce models.

Usage

Estep(p, ref_order, weights, pi_inv)

Arguments

p	Numeric GxK matrix of component-specific support parameters.
ref_order	Numeric GxK matrix of component-specific reference orders.
weights	Numeric vector of the G mixture weights.
pi_inv	Numeric NxK data matrix of partial orderings.

Value

Numeric NxG matrix of estimated posterior component membership probabilities.
