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:

entropy( p ): geometric distribution entropy.
kurtosis( p ): geometric distribution excess kurtosis.
mean( p ): geometric distribution expected value.
median( p ): geometric distribution median.
mode( p ): geometric distribution mode.
skewness( p ): geometric distribution skewness.
stdev( p ): geometric distribution standard deviation.
variance( p ): geometric distribution variance.

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

Geometric( [p] ): geometric distribution constructor.

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 ) );
