Struct HypergeometricRV 

pub struct HypergeometricRV {
    pub n_pop: u64,
    pub k_suc: u64,
    pub n_draw: u64,
}

Hypergeometric distribution: drawing n items from population N with K successes.

Fields

n_pop: u64

k_suc: u64

n_draw: u64

Implementations

impl HypergeometricRV

pub fn new(n_pop: u64, k_suc: u64, n_draw: u64) -> Self

pub fn mean(&self) -> f64

Mean = n * K / N.

pub fn variance(&self) -> f64

Variance = n * K/N * (1 - K/N) * (N-n)/(N-1).
