WebJul 21, 2024 · We can perform a Durbin Watson using the durbin_watson () function from the statsmodels library to determine if the residuals of the regression model are autocorrelated: The test statistic is 2.392. Since this is within the range of 1.5 and 2.5, we would consider autocorrelation not to be problematic in this regression model. WebThe Durbin-Watson tests produces a test statistic that ranges from 0 to 4. Values close to 2 (the middle of the range) suggest less autocorrelation, and values closer to 0 or 4 indicate greater positive or negative autocorrelation respectively.
