Struct probability::distribution::Bernoulli

pub struct Bernoulli { /* fields omitted */ }

A Bernoulli distribution.

Implementations

impl Bernoulli

pub fn new(p: f64) -> Self

Create a Bernoulli distribution with success probability p.

It should hold that p > 0 and p < 1.

pub fn with_failure(q: f64) -> Self

Create a Bernoulli distribution with failure probability q.

It should hold that q > 0 and q < 1. This constructor is preferable when q is very small.

pub fn p(&self) -> f64

Return the success probability.

pub fn q(&self) -> f64

Return the failure probability.
