Gamma

Gamma distribution.

Usage

var gamma = require( '@stdlib/stats/base/dists/gamma' );

Gamma distribution.

var dist = gamma;
// returns {...}

The namespace contains the following distribution functions:

cdf( x, alpha, beta ): gamma distribution cumulative distribution function.
logcdf( x, alpha, beta ): gamma distribution logarithm of cumulative distribution function (CDF).
logpdf( x, alpha, beta ): gamma distribution logarithm of probability density function (PDF).
mgf( t, alpha, beta ): gamma distribution moment-generating function (MGF).
pdf( x, alpha, beta ): gamma distribution probability density function (PDF).
quantile( p, alpha, beta ): gamma distribution quantile function.

The namespace contains the following functions for calculating distribution properties:

The namespace contains a constructor function for creating a gamma distribution object.

var Gamma = require( '@stdlib/stats/base/dists/gamma' ).Gamma;

var dist = new Gamma( 2.0, 4.0 );

var y = dist.cdf( 0.5 );
// returns ~0.594

var objectKeys = require( '@stdlib/utils/keys' );
var gamma = require( '@stdlib/stats/base/dists/gamma' );

console.log( objectKeys( gamma ) );
