Talk:Von Mises-Fisher distribution

From Wikipedia, the free encyclopedia

Presumably it generalizes to a Mises distribution (circle) for p=3, not p=2, since circles are 2-dimensional and the von Mises-Fisher distribution is p-1 dimensional. There might be something I missed though, so I'm not going to change it without confirmation. --Smári McCarthy 13:16, 19 July 2006 (UTC)

The circle is not 2-dimensional, but 1-dimensional, as any point on the circle can be uniquely identified by a singe angle. Similarly, the sphere is 2-dimensional, as each point can be identified by a pair of polar angles. However, you do need an extra dimension to 'represent' the circle or sphere without distortions. --TomixDf Mon Aug 7 12:02:13 2006
