            Example of a test of relative forecasting performance robust to instabilities (Giacomini and Rossi, Journal of Applied Econometrics 2010).

The figure below (implemented via the giacross command in Stata) depicts a sequence of differences of Mean Squared Forecast Error (MSFEs) between two models in rolling windows over time (rescaled by the standard deviation – i.e. a sequence of Diebold and Mariano’s (JBES 1995) test statistics in rolling windows over time). The sequence of MSFEs is depicted in blue in the figure, together with the Giacomini and Rossi’s Fluctuation test critical value lines (in red). Since the sequence of tests is outside the bands, we reject the null hypothesis that the models' forecasting performance is the same in favor of the alternative that the first model forecasts significantly better.
