WebIn threshold-switching dynamic regression models (tsVAR), a state transition occurs when a threshold variable z t crosses a transition mid-level.Discrete transitions result in an abrupt change in the submodel computing the response. Smooth transitions create weighted combinations of submodel responses that change continuously with the value of z t, and … WebAutoregressive (AR) models are some of the most widely used models in applied economics, among other disciplines, because of their generality and simplicity.
