About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

Stats

NPM version Build Status Coverage Status

Statistical functions.

Installation

npm install @stdlib/stats

Alternatively,

  • To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
  • If you are using Deno, visit the deno branch (see README for usage intructions).
  • For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (see README).

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

Usage

var statistics = require( '@stdlib/stats' );

statistics

Namespace containing statistical functions.

var stats = statistics;
// returns {...}

The namespace exposes the following statistical tests:

In addition, it contains an assortment of functions for computing statistics incrementally as part of the incr sub-namespace and functions for computing statistics over iterators in the iterators namespace.

  • incr: incremental statistics.
  • iterators: statistical function iterators.

The base sub-namespace contains functions to calculate statistics alongside a dists namespace containing functions related to a wide assortment of probability distributions.

  • base: base (i.e., lower-level) statistical functions.

Other statistical functions included are:

Examples

var objectKeys = require( '@stdlib/utils/keys' );
var statistics = require( '@stdlib/stats' );

console.log( objectKeys( statistics ) );

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
