Markov-switching model
WebBecause Markov switching models are often characterized by many local maxima of the likelihood function, performing an initial optimization step can be helpful to find the best … WebEstimate Model. Fit the Markov-switching model to the entire unemployment rate series. Monitor convergence of the algorithm by plotting the log-likelihood for each iteration. EstMdl = estimate (Mdl,Mdl0,un,IterationPlot=true); The monotonically increasing log-likelihood is indicative of the behavior of the EM algorithm.
