Struct GeoDist 

pub struct GeoDist {
    pub p: f64,
}

Struct for the geometric distribution X ~ Geo(p) where X = the number of failures prior to observing the first success.

Parameters

• p = probability of success (0 < p <= 1)

Support

• x = 0,1,2,...

Example

Suppose X ~ Geo(p=0.2). Use

use ruststat::GeoDist;
let mut mygeo = GeoDist{p:0.2};
println!("probability mass function: {}", mygeo.pmf(8));
println!("cumulative distribution function: {}", mygeo.cdf(8));
println!("percentile: {}", mygeo.per(0.99));
println!("random: {}", mygeo.ran());
println!("Random vector: {:?}", mygeo.ranvec(5));
println!("mean: {}", mygeo.mean());
println!("variance: {}", mygeo.var());
println!("standard deviation: {}", mygeo.sd());

Fields

p: f64
