WebThe Durbin-Watson test statistic is defined as: ∑ t = 2 T ( ( e t − e t − 1) 2) / ∑ t = 1 T e t 2. The test statistic is approximately equal to 2* (1-r) where r is the sample autocorrelation of the residuals. Thus, for r == 0, indicating no serial correlation, the test statistic equals 2. This statistic will always be between 0 and 4. WebNov 12, 2024 · Fourthly, the Durbin-Watson (1950) test statistic (d = 2.08) (see Table 2) falls within the accepted limits of 1 and 3 (Turner, 2024).
