Trait Implementations

impl Clone for Exponential

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Continuous for Exponential

fn pdf(&self, x: f64) -> f64

Returns f(x) (density / pdf).

fn inv_cdf(&self, p: f64) -> f64

Quantile: F^{-1}(p) for p in (0,1).
