Struct probability::prelude::Laplace

pub struct Laplace { /* fields omitted */ }

A Laplace distribution.

Methods

impl Laplace

pub fn new(mu: f64, b: f64) -> Self

Create a Laplace distribution with location mu and scale b.

It should hold that b > 0.

pub fn mu(&self) -> f64

pub fn b(&self) -> f64
