Self threshold autoregressive model

WebThreshold models are a special case of regime switching models (RSM). In RSM modeling, different models apply to different intervals of values of some key variable (s). Section 5.4 … WebJun 17, 2024 · The analysis of periodic self-exciting threshold integer-valued autoregressive (PSETINAR ) processes was introduced by Pereira et al. [ 25 ]. Manaa and Bentarzi [ 26] established the existence of high moment and the strict periodic stationarity for the PSETINAR processes.

WebThe article “Threshold Estimation via Group Orthogonal Greedy Algorithm” by Ngai Hang Chan, Ching-Kang Ing, Yuanbo Li, and Chun Yip Yau develops a computationally ef-ficient algorithm for estimating a self-exciting threshold au-toregressive model with known autoregressive order and delay, but unknown number of thresholds.

WebOct 31, 2024 · A simple augmentation of the foregoing model is an autoregressive model with a switching trend component: y t = δ 0 + δ 1 t + δ 2 ( t − τ) I ( t > τ) + β y t − 1 + ε t, where τ is the threshold parameter. Such switch can be extended to the whole autoregression. For example, a two-regime AR (p) with drift can be given by: y t = δ 0 ...
