von Mises 分布的检验AI 解读

This paper provides tests in connexion with the von Mises distribution for the circle. The tests are for the concentration parameter and the modal vector of the distribution; they may be adapted to give confidence intervals, and may also be used for a bimodal distribution. New approximations are given for the distributions of the likelihood ratio statistics on which the tests depend.

球面分布离散程度与众数方向的检验AI 解读

This paper provides exact tests in connexion with the distribution introduced by Fisher to describe observations on a sphere. The tests are for the dispersion parameter of the population, and for the modal direction when the dispersion is known. Approximate tests are also examined. The tests may be adapted to provide confidence intervals.
