//! The [`ndarray-stats`] crate exposes statistical routines for `ArrayBase`,
//! the *n*-dimensional array data structure provided by [`ndarray`].
//!
//! Currently available routines include:
//! - [order statistics] (minimum, maximum, median, quantiles, etc.);
//! - [summary statistics] (mean, skewness, kurtosis, central moments, etc.)
//! - [partitioning];
//! - [correlation analysis] (covariance, pearson correlation);
//! - [measures from information theory] (entropy, KL divergence, etc.);
//! - [histogram computation].
//!
//! Please feel free to contribute new functionality! A roadmap can be found [here].
//!
//! Our work is inspired by other existing statistical packages such as
//! [`NumPy`] (Python) and [`StatsBase.jl`] (Julia) - any contribution bringing us closer to
//! feature parity is more than welcome!
