Abstract: In this paper, we review recent work on state space switching models and add some new material on the estimation of parameters of a state space model through the use of the Kalman filter, the expectation-maximization (EM) algorithm and wavelets. We discuss specially switching models where the changes of regimes may be independent or following a Markov chain. We provide a simulation and an application to real data. |
Keywords and phrases: EM algorithm, Kalman filter, Markov chain, state space models, switching models, wavelets. |
