[+] Show declaration

pub struct Beta { /* fields omitted */ }

[−] Expand description

The Beta distribution with shape parameters alpha and beta.

Example

use rand::distributions::{Distribution, Beta};

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

Implementations

impl Beta[−]

pub fn new(alpha: f64, beta: f64) -> Beta[−]

Construct an object representing the Beta(alpha, beta) distribution.

Panics if shape <= 0 or scale <= 0.
