[][src]Struct rand::distributions::Binomial

pub struct Binomial { /* fields omitted */ }

The binomial distribution Binomial(n, p).

This distribution has density function: f(k) = n!/(k! (n-k)!) p^k (1-p)^(n-k) for k >= 0.

Example

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

let bin = Binomial::new(20, 0.3);
let v = bin.sample(&mut rand::thread_rng());
println!("{} is from a binomial distribution", v);

Methods

impl Binomial[src]

pub fn new(n: u64, p: f64) -> Binomial[src]

Construct a new Binomial with the given shape parameters n (number of trials) and p (probability of success).

Panics if p < 0 or p > 1.
