Geometric

Geometric distribution.

Usage

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

geometric

Geometric distribution.

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

The namespace contains the following distribution functions:

  • cdf( x, p ): geometric distribution cumulative distribution function.
  • logcdf( x, p ): geometric distribution logarithm of cumulative distribution function.
  • logpmf( x, p ): geometric distribution logarithm of probability mass function (PMF).
  • mgf( t, p ): geometric distribution moment-generating function (MGF).
  • pmf( x, p ): geometric distribution probability mass function (PMF).
  • quantile( r, p ): geometric distribution quantile function.

The namespace contains the following functions for calculating distribution properties:

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

var Geometric = require( '@stdlib/stats/base/dists/geometric' ).Geometric;

var dist = new Geometric( 0.2 );

var y = dist.logpmf( 3.0 );
// returns ~-2.279

y = dist.logpmf( 2.3 );
// returns -Infinity

Examples

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

console.log( objectKeys( geometric ) );
