Struct rand_distr::Beta

pub struct Beta<F> where
    F: Float,
    StandardNormal: Distribution<F>,
    Exp1: Distribution<F>,
    Open01: Distribution<F>,  { /* fields omitted */ }

The Beta distribution with shape parameters alpha and beta.

Example

use rand_distr::{Distribution, Beta};

let beta = Beta::new(2.0, 5.0).unwrap();
let v = beta.sample(&mut rand::thread_rng());
println!("{} is from a Beta(2, 5) distribution", v);
