In directional statistics, the Kent distribution, also known as the 5-parameter Fisher–Bingham distribution (named after John T. Kent, Ronald Fisher, and Christopher Bingham), is a probability distribution on the unit sphere (2-sphere S in 3-space R ). It is the analogue on S of the bivariate normal distribution with an unconstrained covariance matrix. The Kent distribution was proposed by John … WebSummary.

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 ...
