[−][src]Struct rand::distributions::Beta
The Beta distribution with shape parameters alpha
and beta
.
Example
use rand::distributions::{Distribution, Beta}; let beta = Beta::new(2.0, 5.0); let v = beta.sample(&mut rand::thread_rng()); println!("{} is from a Beta(2, 5) distribution", v);
Methods
impl Beta
[src]
pub fn new(alpha: f64, beta: f64) -> Beta
[src]
Construct an object representing the Beta(alpha, beta)
distribution.
Panics if shape <= 0
or scale <= 0
.
