WebAs a particular case of the Fisher-Bingham distribution on a product-of-spheres, we briefly consider a multicomponent generalization of the Kent (1982) distribution. It turns out that for this distribution, the limiting relative errors of the saddlepoint approximations are zero as con-centration goes to infinity, provided the distribution is ... WebIn statistics, the Bingham distribution, named after Christopher Bingham, is an antipodally symmetric probability distribution on the n-sphere. It is a generalization of the Watson distribution and a special case of the Kent and Fisher-Bingham distributions. The Bingham distribution is widely used in paleomagnetic data analysis, and has been …
