Struct ndarray_rand::rand_distr::ChiSquared[][src]

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

The chi-squared distribution χ²(k), where k is the degrees of freedom.

For k > 0 integral, this distribution is the sum of the squares of k independent standard normal random variables. For other k, this uses the equivalent characterisation χ²(k) = Gamma(k/2, 2).

Example

use rand_distr::{ChiSquared, Distribution};

let chi = ChiSquared::new(11.0).unwrap();
let v = chi.sample(&mut rand::thread_rng());
println!("{} is from a χ²(11) distribution", v)
