Struct rand_distr::ChiSquared [−][src]
pub struct ChiSquared<F> where
F: Float,
StandardNormal: Distribution<F>,
Exp1: Distribution<F>,
Open01: Distribution<F>, { /* fields omitted */ }
Expand description
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)
