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.

Fit a non-linear regression (e.g. spline model like GAM) and then compare it to the linear model using AIC or likelihood ratio test. This is a simple and intuitive method of testing non-linearity. If the test rejects, or if AIC prefers the GAM, then conclude there are non-linearities. Share.

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).
WebTesting and Modeling Threshold Autoregressive Processes. Abstract The threshold autoregressive model is one of the nonlinear time series models available in the literature.
