WebN2 - This study proposes and estimates state-space models with endogenous Markov regime-switching parameters. It complements regime-switching dynamic linear models by allowing the discrete regime to be jointly determined with observed or unobserved continuous state variables. WebThe Markov-switching (MS) model can analyze the time series with structural breaks or different k regime states. The MS model assumes that a hidden Markov chain can be established to represent the unobservable regime k at time t , and estimate the location ( μ k ), scale ( σ k ), and smoothed regime probabilities ( ξ k , t ).
