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.

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.

WebThe Durbin-Watson test is designed for situations in which the only violation of the classical regression model is first-order autocorrelation of the disturbance term. In this case, estimates of ox and P are known to be unbiased but subject to relatively large errors of estimate.
