pmclust (version 0.2-1)

One M-Step: Compute One M-Step Based on Current Posterior Probabilities

Description

This function will perform one M-step based on current posterior probabilities. This is a core function of em.onestep.

Usage

m.step(PARAM)

Arguments

PARAM

a set of parameters.

Value

Returning a new PARAM which maximizes the complete data log likelihood for the current iteration.

Details

This function will base on the current posterior probabilities Z.spmd to estimate the parameters PARAM mainly including mixing proportions ETA, centers of clusters MU, and dispersions of clusters SIGMA.
