Struct rand_distr::FisherF

source · [−]

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

Expand description

The Fisher F distribution F(m, n).

This distribution is equivalent to the ratio of two normalised chi-squared distributions, that is, F(m,n) = (χ²(m)/m) / (χ²(n)/n).

Example

use rand_distr::{FisherF, Distribution};

let f = FisherF::new(2.0, 32.0).unwrap();
let v = f.sample(&mut rand::thread_rng());
println!("{} is from an F(2, 32) distribution", v)
