WebDec 14, 2024 · Recall that the threshold values are only identified up to an interval defined by adjacent values of the sorted threshold variable (Tsay, 1989). For purposes of display, EViews reports the observed value of the threshold variable at the beginning of a regime, truncated to a more readable form, while ensuring that the representation satisfies the … WebNonlinearity tests for time series BY RUEY S.

Unless you have a priori knowledge/information on the type of nonlinearity, it is very difficult to decide the specific form of the model. For instance, there are tests for STAR-type nonlinearities, but they are not built-in. Nevertheless, I believe BDS test could be of help (Series-->View-->BDS Independence test).

WebTesting and Modeling Threshold Autoregressive Processes. Abstract The threshold autoregressive model is one of the nonlinear time series models available in the literature. It was first proposed by Tong (1978) and discussed in detail by Tong and Lim (1980) and Tong (1983).
