Diebold-Mariano Test Statistic
Retrieves the Diebold-Mariano test statistic (1995) for the equality of forecast accuracy of two forecasts under general assumptions.
The function also corrects for the autocorrelation that multi-period forecast errors usually exhibit. Note that an efficient h-period forecast will have forecast errors following MA(h-1) processes. Diebold-Mariano use a Newey-West type estimator for sample variance of the loss differential to account for this concern.
