More Multisample Tests for the von Mises Distribution
GRAHAM J. G. UPTON · Journal of the American Statistical Association · 1976
This article gives three new tests of hypotheses concerning the parameters of von Mises distributions, derived from the likelihood ratio statistics. The two principal tests are for equality of small dispersion parameters where the modal vectors are known and for equality of modal vectors given an unknown common dispersion parameter, assumed large. The tests are simple to use, and are easily adapted for axial data.
