摘要

Samples of directional or axial measurements arise in geophysical, biological and econometric contexts. We represent the rotational difference between two mean directions (or two mean axes) as a direction (or axis). We then construct nonparametric simultaneous confidence sets for all pairwise rotational differences among the mean directions or mean axes of s samples. By specialization, this methodology yields nonparametric simultaneous tests for pairwise equality of directional means or axes.
