Struct probability::prelude::Exponential

pub struct Exponential { /* fields omitted */ }

An exponential distribution.

Methods

impl Exponential

pub fn new(lambda: f64) -> Self

Create an exponential distribution with rate lambda.

It should hold that lambda > 0.

pub fn lambda(&self) -> f64

Return the rate parameter.
