Two Items Concerning Directional Data

Abstract

A discussion is given of confidence procedures for the model vector A of a von Mises or Fisher distribution. Slight revisions of confidence levels are suggested because the usual procedure strictly gives the axis but not the direction of A. The likelihood ratio test is given, with percentage points, for testing A = A sub 0, for the Fisher distribution. A good approximation is offered for the similar test for the von Mises distribution.
