The pairwise distance
Webb5 dec. 2024 · The pairwise-distances method calculates the differences between time-points fine, but doesn’t compare those to zero, instead it compares the delta values to other groups only. because the distances can only be > 0, and hence the equivalent test (null hypothesis: distance == 0) will almost always return a significant result.
