Self-exciting threshold autoregressive
In statistics, Self-Exciting Threshold AutoRegressive (SETAR) models are typically applied to time series data as an extension of autoregressive models, in order to allow for higher degree of flexibility in model parameters through a regime switching behaviour.

The analysis of spatial market integration is important to assess whether to re-establish a dairy processing … WebSuch a collection of models yields a threshold autoregressive model (TAR). z t is the univariate threshold variable. z t can be exogenous to the system or endogenous and delayed. If z t = y k, t − d, the system is a self-exciting threshold autoregressive model (SETAR) with unobserved delay d.

WebAbstract. In this article, we introduce a new random coefficients self-exciting threshold integer-valued autoregressive process. The autoregressive coefficients are driven by a logistic regression structure, so that the explanatory variables can be included. Basic probabilistic and statistical properties of this model are discussed.
