Durbin watson ratio

WebAug 14, 2024 · The Durbin Watson (DW) statistic is a test for autocorrelation of the residuals from a statistical regression analysis. The DW statistic will always have a value between 0 and 4. A value of 2.0 means that there is no autocorrelation detected in the sample. Values from 0 to less than 2 indicate positive autocorrelation and values from 2 … Webmann ratio (von Neumann 1941), the Durbin-Watson sta-tistic (Durbin and Watson 1950, 1951), the Theil BLUS procedure (Theil 1965, 1968; Theil and Nagar 1961), the Henshaw test (Henshaw 1966), the Geary test (Geary 1970), the Abrahamse-Louter test (Abrahamse and Lou-ter 1971), and the Berenblut-Webb test (Berenblut and Webb 1973).
