Web3 sep. 2024 · Markov-switching models offer a powerful tool for capturing the real-world behavior of time series data. Today's blog provides an introduction to Markov-switching models including: What a regime switching model is and how it differs from a structural break model. When we should use the regime switching model. What a Markov … Weba Markov switching model in which either the mean, the variance, or both may diﬀer between two regimes. Hamilton and Susmel (1993) propose a model with sudden discrete changes in the process which governs volatility. They found that a Markov switching process provides a better statistical ﬁt to the data than GARCH models without switching.
