TD_DURBIN_WATSON

It is a test which looks for the presence of serial correlation amongst the error/residual terms. It is mainly employed to analyze the residuals produced by a univariate or multivariate regression (cross-sectional data sets). With respect to regression models, it is expected that there would exist no serial correlation amongst the error terms in contrast, with time series, the expectation is that most likely their will exist serial correlation amongst the error terms.
