WebWhen data set of interest is a time series data, we may want to compute the 1st-order autocorrelation for the variables of interest and to test if the autocorrelation is zero. One … WebIf we choose α = 0.05, then Table 2 gives the critical values correspond-ing to n = 20 and one regressor as dL = 1.20 and dU = 1.41. ∵ d = 1.08 < dL = 1.20 ∴ We reject H0 and conclude that the errors are positively autocorre-lated.

WebThe Durbin-Watson statistic is zero in large samples, if there is no autocorrelation The critical value of Durbin-Watson test at certain significance level can be found in the statistical tables. It is possible that we cannot make testing decision given the calculated Durbin-Watson statistic and the significance level of the test.
