Bibliography: Durbin-Watson (DW) check is a commonly employed evaluation for autocorrelated errors. The procedures based upon Newbold et al. (2010)'s study are summarized since follow:

The null hypothesis: H0: ПЃ=0

The DW figure (d = 1 . 76157) in this analyze is obtained by using Minitab. Then intended for given in (the volume of observations=570), t (the volume of independent variables=1) and significance level of 5%, values of dL and dU can be acquired.
