Struct FDist 

pub struct FDist {
    pub nu1: f64,
    pub nu2: f64,
}

Struct for the F distribution X ~ F(nu1, nu2).

Parameters

• nu1 > 0
• nu2 > 0

Support

• x > 0

Example

Suppose X ~ F(nu1=4.0, nu2=18.0). Use.

use ruststat::FDist;
let mut myf = FDist{nu1:4.0, nu2:18.0};
println!("Probability density function f(2.5): {}", myf.pdf(2.5));
println!("Cumulative distribution function P(X<=2.5): {}", myf.cdf(2.5));
println!("99th percentile: {}", myf.per(0.99));
println!("Random draw: {}", myf.ran());
println!("Random vector: {:?}", myf.ranvec(5));
println!("Mean: {}", myf.mean());
println!("Variance: {}", myf.var());
println!("Standard deviation: {}", myf.sd());

Fields

nu1: f64

nu2: f64
