WebDurbin-Watson test A test that the residuals from a linear regression or multiple regression are independent. Method: Because most regression problems involving time series data exhibit positive autocorrelation, the hypotheses usually consid-ered in the Durbin-Watson test are H0: ρ = 0 H1: ρ > 0 The test statistic is d = Pn i=2(ei −ei−1 ... WebIn statistics, the Durbin–Watson statistic is a test statistic used to detect the presence of autocorrelation at lag 1 in the residuals (prediction errors) from a regression analysis. It is named after James Durbin and Geoffrey Watson. The small sample distribution of this ratio was derived by John von Neumann (von Neumann, 1941).
