The Durbin-Watson statistic is used to test for autocorrelation, which is a violation of the assumption of independence among residuals. If the Durbin-Watson statistic falls between 0 and 4, and is close to 2, then the residuals are likely independent. If the statistic is closer to 0, then there is positive autocorrelation, and if it is closer to 4, then there is negative autocorrelation. Additionally, other diagnostic plots such as a plot of residuals vs. time can also be used to assess independence.
