Struct rand::distributions::StudentT

pub struct StudentT { /* fields omitted */ }

The Student t distribution, t(nu), where nu is the degrees of freedom.

Example

use rand::distributions::{StudentT, Distribution};

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

Methods

impl StudentT

pub fn new(n: f64) -> StudentT

Create a new Student t distribution with n degrees of freedom. Panics if n <= 0.
