The **Kent distribution**, also known as the *5-parameter Fisher-Bingham distribution*, is a probability distribution in ℜ^{3}, the real three dimensional coordinate space, of a two-dimensional unit sphere.

## Kent Distribution PDF

The Kent distribution’s probability density function, f(x), is given by the equation:

Here,

- x is a three dimensional unit value.
- c(κ, β) is a normalizing constant, and is given by the equation

In the above equation, I_{v}(κ) represents what is called the modified Bessel function.
