Struct Bernoulli 

pub struct Bernoulli { /* private fields */ }

Bernoulli Distribution

Example Usage

let mut bernoulli = rand_simple::Bernoulli::new(1192u32);

// Default parameters
assert_eq!(format!("{bernoulli}"), "Bernoulli(Probability) = Bernoulli(0.5)");
println!("Does the event occur (1) or not (0) with a probability θ = 0.5? -> {}", bernoulli.sample());

// Updating the probability parameter
let probability: f64 = 0.8f64;
let result: Result<f64, &str> = bernoulli.try_set_params(probability);
assert_eq!(format!("{bernoulli}"), "Bernoulli(Probability) = Bernoulli(0.8)");
println!("Does the event occur (1) or not (0) with a probability θ = {}? -> {}", probability, bernoulli.sample());

Implementations

impl Bernoulli

pub fn new(_seed: u32) -> Self

コンストラクタ

• _seed - 乱数の種

pub fn sample(&mut self) -> u64

ある確率の事象が生じたか(1u64)、否か(0u64)を返す

pub fn try_set_params(&mut self, probability: f64) -> Result<f64, &str>

確率変数のパラメータを変更する

• probability - 尺度母数

Trait Implementations

impl Display for Bernoulli
