Dynamic linear models with markov-switching
WebJul 1, 2002 · Bayesian estimation of a very general model class where the distribution of the observations is assumed to depend on a latent mixture or switching variable taking values in a discrete state space is discussed, e.g. finite mixture modelling, Markov switching autoregressive modelling and dynamic linear models with switching. Expand WebJun 6, 2006 · For long-lived assets such as bridges, the time-homogeneity assumptions of Markov chains should be carefully checked. For this purpose, this research proposes a regime-switching continuous-time Markov chain of which the state transition probabilities depend on another, latent, Markov chain that characterizes the overall aging regime of …

WebIt complements regime-switching dynamic linear models by allowing the discrete regime to be jointly determined with observed or unobserved continuous state variables. The estimation framework involves a Bayesian Markov chain Monte Carlo scheme to simulate the latent state variable that controls the regime shifts. Web4 C.-J.

WebJul 27, 2007 · Switching Linear Dynamic System (SLDS) models are a popular technique for modeling complex nonlinear dynamic systems. An SLDS can describe complex temporal patterns more concisely and accurately than an HMM by using continuous hidden states. However, the use of SLDS models in practical applications is challenging for three reasons. WebDynamic linear models with Markov regime-switching parameters are widely used in empirical macroeconomics and nance because of their exibility. This exibility is attributed to two types of unobserved state variables in the model: continuous latent variables following an autoregressive process and discrete latent variables governed by a
