Durbin-Watson test and biological (non time-series) data. 3. Best practice of testing for serial correlation in VAR residuals in R. 4. WebThe Harvey-Collier test indicates whether the residuals are linear, while the Rainbow test discerns whether a linear model is appropriate even if some underlying relationships are not linear. The Rainbow test is useful here; the basic idea is that if the true relationship is non-linear, a good linear fit can be achieved on a subsample in the ...

WebDetails: The Harvey-Collier test performs a t-test (with parameter degrees of freedom) on the recursive residuals. If the true relationship is not linear but convex or concave the mean of the recursive residuals should differ from 0 significantly.
