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). The major features of this class of models are limit cycles, amplitude ... Weblinear hypotheses; see[R] test. testnl is the only option for testing linear and nonlinear hypotheses simultaneously. Options mtest (opt) specifies that tests be performed for each condition separately. opt specifies the method for adjusting p-values for multiple testing. Valid values for opt are bonferroni Bonferroni’s method holm Holm’s ...

WebLikelihood ratio test for threshold nonlinearity Description. Carry out the likelihood ratio test for threshold nonlinearity, with the null hypothesis being a normal AR process and the alternative hypothesis being a TAR model with homogeneous, normally distributed errors.

WebJan 1, 1999 · Tsay test stands out for the data generated from a threshold autoregression (TAR) process, but even there the BDS test still has reasonable power. We conclude that the BDS test is the best test
WebMay 10, 2014 · Glenn is right. 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).
