Spherical Fisher-Bingham distribution

Simulation of random values from a spherical Fisher-Bingham distribution.

Usage

rfb(n = 100, mu = Vec3(1, 0, 0), k = 5, A)

Arguments

n

integer. number of random samples to be generated

mu

Mean vector. object of class "Vec3", "Line", "Ray", or "Plane", where the rows are the observations and the columns are the coordinates.

k

numeric. The concentration parameter (\(\kappa\)) of the von Mises-Fisher distribution

A

symmetric matrix

x <- rfb(100, mu = Line(120, 50), k = 5, A = diag(c(-1, 0, 1)))
