Abstract
Based on independent samples, tests for homogeneity of distributions for compositional and directional data models are considered. Rao's (modified) scores statistics in conjunction with an alignment procedure are incorporated in the formulation of suitable randomisation tests which avoid the complications of likelihood based parametrics and exploit the Chatterjee-Sen (multivariate) permutation principle for such shape distributions. Our proposed tests amend readily to other directional data models. Finite as well as large sample size properties of the proposed tests are presented.
