Mean

Examples
#[macro_use]
extern crate peroxide;
use peroxide::fuga::*;

fn main() {
    let a = c!(1,2,3,4,5);
    assert_eq!(a.mean(), 3.0);
}

Variance

Examples
#[macro_use]
extern crate peroxide;
use peroxide::fuga::*;

fn main() {
    let a = c!(1,2,3,4,5);
    assert_eq!(a.var(), 2.5);
}

Standard Deviation

Examples
#[macro_use]
extern crate peroxide;
use peroxide::fuga::*;

fn main() {
    let a = c!(1,2,3);
    assert!(nearly_eq(a.sd(), 1f64)); // Floating Number Error
}
