    pub alpha: f64,
    pub beta: f64,
}

Beta distribution X ~ Beta(alpha, beta).

Fields

Implementations

impl BetaRV

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

pub fn mean(&self) -> f64

Mean = alpha / (alpha + beta).

pub fn variance(&self) -> f64

Variance = alpha*beta / ((alpha+beta)^2 * (alpha+beta+1)).

pub fn mode(&self) -> Option<f64>

Mode = (alpha-1)/(alpha+beta-2) for alpha,beta > 1.
