WebMar 9, 2024 · Test for Autocorrelation. The Durbin-Watson statistic is commonly used to test for autocorrelation. It can be applied to a data set by statistical software. The outcome of the Durbin-Watson test ranges from 0 to 4. An outcome closely around 2 means a very low level of autocorrelation. WebThe Durbin-Watson test statistic is defined as: ∑ t = 2 T ( ( e t − e t − 1) 2) / ∑ t = 1 T e t 2.
