Struct rand::distributions::Beta

source · [−]

pub struct Beta { /* private fields */ }

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

source

impl Beta

source

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