Web4.3.2 Threshold representation Bivariate threshold models are complicated by the possibility that a bivariate pair (x,y) may be an ‘exceedance’ and yet exceed the … Webary. Compared to the ordinary threshold model, where typi-cal the lag variable xt-' is the threshold variable, this is a somewhat indirect way of formulating a nonstationary threshold VAR model. In this article, we start directly from the VAR representation (1.1) and then move to the threshold VAR representation (1.4)
