Combining Volatility Forecasts of Duration‐Dependent Markov‐Switching Models

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Duration‐dependent Markov‐switching (DDMS) models require a user‐specified duration hyperparameter, for which there is currently no established procedure for estimation or testing. As a result, an ad‐hoc duration choice must be heuristically justified.
