Intro to Biostatistics
The Durbin-Watson statistic is a measure used to detect the presence of autocorrelation in the residuals from a regression analysis. It helps to assess whether the residuals, which are the differences between observed and predicted values, are correlated across time or space. A value close to 2 suggests no autocorrelation, while values approaching 0 or 4 indicate positive or negative autocorrelation, respectively, impacting the reliability of model predictions.
congrats on reading the definition of Durbin-Watson statistic. now let's actually learn it.
