WebDec 6, 2024 · The Durbin Watson statistic is a test statistic used in statistics to detect autocorrelation in the residuals from a regression analysis. The Durbin Watson statistic will always assume a value between 0 and 4. A … WebThe construction of this statistic means that it can take values between 0 and 4. We have \( { d = 2 } \) when \( { \widehat{\rho} = 0 } \).We denote the sample estimate of the observation of ρ by \( { \widehat{\rho} } \).In order to test the hypothesis H 0, Durbin and Watson tabulated the critical values of d at a significance level of 5%; these critical values …
