Fisher bingham distribution
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 … WebApr 9, 2024 · The sum of such steps is again a Gaussian vector with expectation n · d, and its central projection onto the unit sphere gives the angular Gaussian distribution or Bingham distribution, since Bingham was the first to explicitly derive the probability density function as an infinite series (see also the implicit formula in ).
