[−][src]Struct nannou::rand::distributions::Poisson
The Poisson distribution Poisson(lambda)
.
This distribution has a density function:
f(k) = lambda^k * exp(-lambda) / k!
for k >= 0
.
Example
use rand::distributions::{Poisson, Distribution}; let poi = Poisson::new(2.0); let v = poi.sample(&mut rand::thread_rng()); println!("{} is from a Poisson(2) distribution", v);
Methods
impl Poisson
[src]
pub fn new(lambda: f64) -> Poisson
[src]
Construct a new Poisson
with the given shape parameter
lambda
. Panics if lambda <= 0
.
