If et is the residual given by the Durbin-Watson test statistic is where T is the number of observations. For large T, d is approximately equal to 2(1 − ), where is the sample autocorrelation of the residuals, d = 2 therefore indicates no autocorrelation. The value of d always lies between 0 and 4. If the Durbin–Watson statistic is substantially less than 2, there is evidence of positive serial correlation. As a rough rule of thumb, if Durbin–Watson is less tha… WebThe Durbin-Watson statistic ranges from 0 to 4, and is always between 0 and 4. This value less than 2 may indicate positive serial correlation, while a value of two or more indicates negative serial correlation.
