Function standard_deviation 

pub fn standard_deviation<T: AsRef<[f32]>>(values: T) -> f32

Calculate statistical standard deviation for values.

Return NaN if the values are empty.

Filter NaN values in the stream.

Example

#[macro_use]
use numeric_statistics::assert_eq_f32;
use numeric_statistics::f32::standard_deviation::*;
let values = &[1.0, 2.0, 4.0];
let standard_deviation = standard_deviation(values);
assert_eq_f32!(standard_deviation, 1.5275253 as f32);
