Bernoulli

Bernoulli distribution.

Usage

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

bernoulli

Bernoulli distribution.

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

The namespace contains the following distribution functions:

cdf( x, p ): Bernoulli distribution cumulative distribution function.
mgf( t, p ): Bernoulli distribution moment-generating function (MGF).
pmf( x, p ): Bernoulli distribution probability mass function (PMF).
quantile( r, p ): Bernoulli distribution quantile function.

The namespace contains the following functions for calculating distribution properties:

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

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

Bernoulli( [p] ): Bernoulli distribution constructor.

var Bernoulli = require( '@stdlib/stats/base/dists/bernoulli' ).Bernoulli;

var dist = new Bernoulli( 0.2 );

var y = dist.pmf( 0.0 );
// returns 0.8

y = dist.pmf( 1.0 );
// returns 0.2

Examples

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

console.log( objectKeys( bernoulli ) );
