Struct HyperGeometric 

pub struct HyperGeometric {
    pub big_n: usize,
    pub big_t: usize,
    pub n: usize,
    pub x: usize,
}

Tracks parameters mapping states across Hypergeometric sample space distributions where sampling occurs without replacement.

Fields

big_n: usize

Total items present inside the master population base ($N$).

big_t: usize

Total characteristic target elements tracked inside the population ($T$).

n: usize

Number of elements drawn in the sample slice ($n$).

x: usize

Tracked number of matching characteristics observed inside the sample ($x$).

Implementations
