Struct GeometricRV 

pub struct GeometricRV {
    pub p: f64,
}

Geometric random variable X ~ Geom(p) (number of trials until first success).

Fields

p: f64

Implementations

impl GeometricRV

pub fn new(p: f64) -> Self

pub fn mean(&self) -> f64

Mean = 1/p.

pub fn variance(&self) -> f64

Variance = (1-p)/p^2.

pub fn pmf(&self, k: u64) -> f64

PMF: P(X=k) = (1-p)^(k-1) * p for k >= 1.

pub fn cdf(&self, k: u64) -> f64

CDF: P(X <= k) = 1 - (1-p)^k.
