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 ) );
