Most papers in the literature determine this by checking when it changes from being a linear trend to a quadratric trend. i.e deviation from linearity is seen as evidence that the second, slower process is used. I'd like to test the ranges 1-2, 1-3, 1-4, 1-5, 1-6, etc and see when a qudratric trend is significant. However, although I have read some literature and done many google searches, I cannot figu...
