ExpectationM_MSVARmdl

This function computes the log-likelihood for a markov-switching vector autoregressive model and uses the Hamilton smoother to obtain smoothed probabilities of each state. This is also the expectation step in the Expectation Maximization algorithm for a Markov-switching autoregressive model.
