Webb26 jan. 2024 · To evaluate the significance of each score in each observation, permutation test is performed by randomly shuffling values of the observation and recalculating scores, so for observation i, I have random scores s 1 i r = { s 1 i 1, s 1 i 2,..., s 1 i R } and s 2 i r = { s 2 i 1, s 2 i 2,..., s 2 i R }, where R is number of permutations. R = 10000.
