Struct probability::distribution::Lognormal

pub struct Lognormal { /* fields omitted */ }

A lognormal distribution.

Methods

impl Lognormal

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

Create a lognormal distribution with location mu and scale sigma.

It should hold that sigma > 0.

pub fn mu(&self) -> f64

Return the location parameter.

pub fn sigma(&self) -> f64

Return the scale parameter.
