Function rstats::median

pub fn median(data: &[i64]) -> Result<Med>

Fast median (avoids sorting).
The data values must be within a moderate range not exceeding u16size (65535).

Example

use rstats::median;
const VEC1:[i64;14] = [1,2,3,4,5,6,7,8,9,10,11,12,13,14];
let res = median(&VEC1).unwrap();
assert_eq!(res.median,7.5_f64);
assert_eq!(res.lquartile,4_f64);
assert_eq!(res.uquartile,11_f64);
