Durbin Watson Statistic: How to detect Autocorrelation in SPSS?

WebFor ρ < 0 the test is 4-DW (2.207), everything else is similar (e.g. if 4 − D W < d L → c o n c l u d e ρ < 0) But like I said above, since you've carried these two tests out seperately, if you've tested them both at the α = 0.05 level, then you don't have the two sided test at that level. You've got the test at the 2 α level. 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.
