In statistics, the Bingham distribution, named after Christopher Bingham, is an antipodally symmetric probability distribution on the ''n''-sphere.〔Bingham, Ch. (1974) "An antipodally symmetric distribution on the sphere". ''Annals of Statistics'', 2(6):1201–1225.〕 It is widely used in paleomagnetic data analysis,〔Onstott, T.C. (1980) "Application of the Bingham distribution function in paleomagnetic studies". ''Journal of Geophysical Research'', 85:1500–1510.〕 and has been reported as being of use in the field of computer vision.〔 S. Teller and M. Antone (2000). ''Automatic recovery of camera positions in Urban Scenes''〕 Its probability density function is given by : which may also be written : where x is an axis, ''M'' is an orthogonal orientation matrix, ''Z'' is a diagonal concentration matrix, is a confluent hypergeometric function of matrix argument. ==See also== * Directional statistics * Kent distribution 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Bingham distribution」の詳細全文を読む スポンサード リンク
