Expand description

The Dirichlet distribution Dirichlet(alpha).

The Dirichlet distribution is a family of continuous multivariate probability distributions parameterized by a vector alpha of positive reals. It is a multivariate generalization of the beta distribution.

Example

use rand::prelude::*;
use rand_distr::Dirichlet;

let dirichlet = Dirichlet::new(&[1.0, 2.0, 3.0]).unwrap();
let samples = dirichlet.sample(&mut rand::thread_rng());
println!("{:?} is from a Dirichlet([1.0, 2.0, 3.0]) distribution", samples);

Implementations

Construct a new Dirichlet with the given alpha parameter alpha.

Requires alpha.len() >= 2.

Construct a new Dirichlet with the given shape parameter alpha and size.

Requires size >= 2.
