Function standard_deviation_with_variance 

pub fn standard_deviation_with_variance(variance: f64) -> f64

Calculate statistical standard deviation for values, given a pre-calculated variance value.

Return NaN if the values are empty.

Filter NaN values in the stream.

Example

#[macro_use]
use numeric_statistics::assert_eq_f64;
use numeric_statistics::f64::{variance::*, standard_deviation::*};
let values = &[1.0, 2.0, 4.0];
let variance = variance(values);
let standard_deviation = standard_deviation_with_variance(variance);
assert_eq_f64!(standard_deviation, 1.5275252316519465 as f64);
