The CW statistic adjusts the Diebold and Mariano (1995) and West (1996) (henceforth, DMW test) statistic to correct for size distortions. If two models are non-nested, the DMW test is appropriate to compare the mean square prediction errors (MSPE ... WebClark and West (2007) thus provide a very convenient method for assessing statistical significance when comparing nested forecasts that obviates the need to look up a new set of critical values for each application. The MSFE-adjusted statistic is straightforward to compute by first defining (42)
