Distribution‐free R sample tests for the hypothesis of parallelism of response profiles
Norbert Pyhel · Biometrical Journal · 1980
Abstract In this paper two nonparametric tests are given for testing the nullhypothesis of parallelity of response curves in r samples. The first procedure is done by a permutation test, whose practical applicability is ensured by a FORTRAN‐subroutine available from the author. As the computational work and time grows rapidly with sample sizes, a Monte‐Carlo‐solution is optionally given by the same procedure. Alternatively an asymptotically distribution‐free test based on quadratic forms is constructed for large sample situations.
