Has anybody implemented the Vogelsang test from Vogelsang's 1998 Econometrica paper? Or the tests by Fomby and Vogelsang from their 2002 paper? I have been looking for trends in many time series (1000's) with unknown autocorrelation. In brief, I have fit AR models and classified them as stochastic or deterministic with augmented Dickey-Fuller tests. A colleague has suggested that we use a "new and more elegant test" that is robust to the nature of serial correlation in the residuals and pointed me the RATS program in general and Fomby and Vogelsang test in particular. Any leads appreciated, Andy ~~~~~~~~~~~~~~ Fomby TB, Vogelsang TJ, The application of size-robust trend statistics to global-warming temperature series.
