WebTo find the p-value for this test statistic we need to look up a Durbin-Watson critical values table, which in this case indicates a highly significant p-value of approximately 0. (In general Durbin-Watson statistics close to 0 suggest significant positive autocorrelation.) A lag of 1 appears appropriate.

The test statistic for the Durbin-Watson test, typically denoted d, is calculated as follows: where: T: The total number of observations et: The tth residual from the regression model The test statistic always ranges from 0 to 4 where: d = 2 indicates no autocorrelation d < 2 indicates positive serial correlation See more The Durbin-Watson test uses the following hypotheses: H0 (null hypothesis): There is no correlation among the residuals. HA (alternative hypothesis): The residuals are autocorrelated. … See more For step-by-step examples of Durbin-Watson tests, refer to these tutorials that explain how to perform the test using different statistical software: How to Perform a Durbin-Watson Test in R How to Perform a Durbin … See more If you reject the null hypothesis of the Durbin-Watson test and conclude that autocorrelation is present in the residuals, then you have a few different options to correct this problem … See more WebThe Durbin-Watson test statistic is defined as: The test statistic is approximately equal to 2* (1-r) where r is the sample autocorrelation of the residuals.
