Struct probability::prelude::Logistic

pub struct Logistic { /* fields omitted */ }

A logistic distribution.

Methods

impl Logistic

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

Create a logistic distribution with location mu and scale s.

It should hold that s > 0.

pub fn mu(&self) -> f64

Return the location parameter.

pub fn s(&self) -> f64

Return the scale parameter.
