Struct flow_sdk::algorithms::rand::distributions::Beta

pub struct Beta { /* fields omitted */ }

The Beta distribution with shape parameters alpha and beta.

Example

use rand::distributions::{Distribution, Beta};

let beta = Beta::new(2.0, 5.0);
let v = beta.sample(&mut rand::thread_rng());
println!("{} is from a Beta(2, 5) distribution", v);

Implementations

impl Beta

pub fn new(alpha: f64, beta: f64) -> Beta

Construct an object representing the Beta(alpha, beta) distribution.

Panics if shape <= 0 or scale <= 0.

Trait Implementations

impl Clone for Beta

pub fn clone(&self) -> Beta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Beta

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Distribution<f64> for Beta

pub fn sample<R>(&self, rng: &mut R) -> f64 where
    R: Rng + ?Sized, 

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R>(&'a self, rng: &'a mut R) -> DistIter<'a, Self, R, T> where
    R: Rng, 

Create an iterator that generates random values of T, using rng as the source of randomness.
