A general-purpose method for two-group randomization tests
We outline a novel approach to calculate exact p-levels for two-sample randomization tests. The approach closely resembles permute in its applications, with the main diﬀerence being that the results are approximated only if the execution time needed to calculate exact p-levels would exceed a speciﬁed maximum. We demonstrate its use by deriving p-levels for the signiﬁcance of Somers’ D, the coefficient of variation, the diﬀerence in means and in medians, and the difference in two multinomials.
