Trait probability::distribution::Variance

pub trait Variance: Mean {
    fn variance(&self) -> f64;

    fn deviation(&self) -> f64 { ... }
}

A distribution capable of computing the variance.

The trait is applicable when the variance exists, that is, finite.

Required Methods

fn variance(&self) -> f64

Compute the variance.

Provided Methods

fn deviation(&self) -> f64

Compute the standard deviation.
