[][src]Struct rand::distributions::Dirichlet

pub struct Dirichlet { /* fields omitted */ }
Deprecated since 0.7.0:

moved to rand_distr crate

The dirichelet 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.

Methods

impl Dirichlet[src]

pub fn new<V: Into<Vec<f64>>>(alpha: V) -> Dirichlet[src]

Construct a new Dirichlet with the given alpha parameter alpha.

Panics

  • if alpha.len() < 2

pub fn new_with_param(alpha: f64, size: usize) -> Dirichlet[src]

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

Panics

  • if alpha <= 0.0
  • if size < 2
