Webis the Durbin-Watson (DW) statistic. The DW stat measures the ratio of the sum of squared difference in pairs of residuals to the sum of squared residuals for each observation alone. The formula for the statistic is not particularly important – Stata will calculate it for you. What is important is understanding the complex interpretation of it.

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.
