Hypergeometric

Hypergeometric distribution.

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 ) );
