...als(fm)[-1]) stats::Box.test(residuals(fm)) lmtest::dwtest(fm, alternative="two.sided") lmtest::bgtest(fm, type="F") In my model, a simple lm(y~x1+x2) with n=20 annual measurements, I have significant _positive_ autocorrelation within Y and within both X vectors, but _negative_ autocorrelation in the residuals. The residual autocorrelation is not quite significant, with the p-values 0.070 0.064 0.125 0.077 from the tests above. I seem to remember some authors saying that the Durbin-Watson test has less power than some alternative tests, as reflected here....

...n data with much more components than data points? Did you observe bad overfitting, too? Any other observations? * Why might the lars (least angle regression from lars package) method produce beta values that shoot up into the sky (until they overflow), and why might the Cp values start at a _negative_ value in step 1, growing linearly? That's not normal behaviour. What might be wrong there? For details see my last mail. :) Regards, Wiebke
