The Durbin-Watson Statistic (DW) is approximated by: DW = 2(1−r) D W = 2 ( 1 − r) Where: r r = Sample correlation between regression residuals from one period and the previous period.

WebThe Durbin-Watson test is a widely used method of testing for autocorrelation. The first-order Durbin-Watson statistic is printed by default. This statistic can be used to test for first-order autocorrelation. Use the DWPROB option to print the significance level ( p -values) for the Durbin-Watson tests. WebThe d' test is also found to be more powerful than its counterpart against negative autocorrelation and for small values of the autocorrelation coefficient against positive autocorrelation. Selected bounds for significance points of d' are tabulated. ... T1 - The alternative Durbin-Watson test. An assessment of Durbin and Watson's choice of ... crypto deposit accounts

WebThe Durbin-Watson tests produces a test statistic that ranges from 0 to 4. Values close to 2 (the middle of the range) suggest less autocorrelation, and values closer to 0 or 4 indicate greater positive or negative autocorrelation respectively.
