Dynamic factor 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 parameters. Below, we specify that 20 random perturbations from the starting parameter vector are examined and the best one used as the actual starting parameters. WebMarkov-switching model where the evolution of the GDP is split between recession and expansion phases. Handling both characteristics within a single uni ed model was rst proposed byDiebold and Rudebusch(1996) and accomplished by bothChauvet(1998) andKim and Nelson(1998) adopting a multivariate dynamic factor Markov-switching …

Weblinear model for GDP. We present Bayesian tests for Markov switching in both univariate and multivariate settings based on sensitivity of the posterior probability to the prior. We ¯nd that evidence for Markov switching, and thus the business cycle asymmetry, is stronger in a switching version of the dynamic factor model of Stock and Watson (1991) WebFor this purpose, we conduct a “beauty contest” among three different Markov-switching approaches: a traditional Markov-Switching (MS) … shytown music https://frenchtouchupholstery.com
