Contour plots of the von Mises-Fisher distribution on the sphere.
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.
