Function rgsl::statistics::skew_m_sd

pub fn skew_m_sd(data: &[f64], stride: usize, n: usize, mean: f64, sd: f64) -> f64

This function computes the skewness of the dataset data using the given values of the mean mean and standard deviation sd,

skew = (1/N) \sum ((x_i - mean)/sd)³

These functions are useful if you have already computed the mean and standard deviation of data and want to avoid recomputing them.
