WebApplying this permutation to the preference profile, we get: f(X, Y, Y, X) = X. f(Y, X, X, Y) = Y Therefore, the voting rule is equitable. To show that this voting rule does not belong to the family of threshold rules, we can consider the following preference profile: A: X > Y. B: Y > X. C: X > Y. D: Y > X Web2.1 Permutation Thresholds and p-Values Following Churchill and Doerge (1994), let individuals in the QTL experiment be indexed from 1 to n and let N denote the number of randomly selected data permutations for which test statistics at all analysis points are recomputed.
