The concentration parameter. |
The user specifies the concentration parameter only and not the mean direction or data. This is for illustration purposes only. The graph will always contain circles, as the von Mises-Fisher distribution is the analogue of a bivariate normal in two dimensions with a zero covariance.
A contour plot of the von Mises-Fisher distribution.
