WebNov 21, 2024 · The Durbin-Watson statistic ranges between 0 and 4. A value of 2.0 means that there is no autocorrelation. Values between 0 and 2 indicate positive and values between 2 and 4 indicate negative autocorrelation. In our case, Durbin-Watson statistic is very close to 2.0 therefore we can say that no autocorrelation assumption is not violated. WebNov 12, 2024 · Dubrin-Watson test (DW) was used for autocorrelation of the prediction errors in the regression model. A value of DW between 1.5 and 2.5 was considered normal [31].

How can I compute Durbin-Watson statistic and 1st order autocorrelation ...

WebRecall that the formula relating the value of the Durbin Watson (DW) statistic, and the coefficient of first order autocorrelation, p, is: DW is approximately equal to 2(1-p) Thus, if DW is close to zero, the first order autocorrelation coefficient, p, must be close to +1. A value of p close to -1 would suggest negative autocorrelation, while a ...
