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!
Hypergeometric
Hypergeometric distribution.
Installation
npm install @stdlib/stats-base-dists-hypergeometric
Usage
var hypergeometric = require( '@stdlib/stats-base-dists-hypergeometric' );
hypergeometric
Hypergeometric distribution.
var dist = hypergeometric;
// returns {...}
The namespace contains the following distribution functions:
-
cdf( x, N, K, n )
: hypergeometric distribution cumulative distribution function. -
logpmf( x, N, K, n )
: evaluate the natural logarithm of the probability mass function (PMF) for a hypergeometric distribution. -
pmf( x, N, K, n )
: hypergeometric distribution probability mass function (PMF). -
quantile( p, N, K, n )
: hypergeometric distribution quantile function.
The namespace contains the following functions for calculating distribution properties:
-
kurtosis( N, K, n )
: hypergeometric distribution excess kurtosis. -
mean( N, K, n )
: hypergeometric distribution expected value. -
mode( N, K, n )
: hypergeometric distribution mode. -
skewness( N, K, n )
: hypergeometric distribution skewness. -
stdev( N, K, n )
: hypergeometric distribution standard deviation. -
variance( N, K, n )
: hypergeometric distribution variance.
The namespace contains a constructor function for creating a hypergeometric distribution object.
-
Hypergeometric( N, K, n )
: hypergeometric distribution constructor.
var Hypergeometric = require( '@stdlib/stats-base-dists-hypergeometric' ).Hypergeometric;
var dist = new Hypergeometric( 8, 2, 4 );
var y = dist.cdf( 0.5 );
// returns ~0.214
Examples
var objectKeys = require( '@stdlib/utils-keys' );
var hypergeometric = require( '@stdlib/stats-base-dists-hypergeometric' );
console.log( objectKeys( hypergeometric ) );
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.
