Package Exports

@stdlib/stats-base-dists-bernoulli

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/stats-base-dists-bernoulli) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Bernoulli

Bernoulli distribution.

Installation

npm install @stdlib/stats-base-dists-bernoulli

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 ) );

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
