Package Exports

@stdlib/stats-base-dists-logistic

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-logistic) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Logistic

Logistic distribution.

Installation

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

Usage

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

logistic

Logistic distribution.

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

The namespace contains the following distribution functions:

cdf( x, mu, s ): logistic distribution cumulative distribution function.
logcdf( x, mu, s ): logistic distribution logarithm of cumulative distribution function.
logpdf( x, mu, s ): logistic distribution logarithm of probability density function (PDF).
mgf( t, mu, s ): logistic distribution moment-generating function (MGF).
pdf( x, mu, s ): logistic distribution probability density function (PDF).
quantile( p, mu, s ): logistic distribution quantile function.

The namespace contains the following functions for calculating distribution properties:

entropy( mu, s ): logistic distribution differential entropy.
kurtosis( mu, s ): logistic distribution excess kurtosis.
mean( mu, s ): logistic distribution expected value.
median( mu, s ): logistic distribution median.
mode( mu, s ): logistic distribution mode.
skewness( mu, s ): logistic distribution skewness.
stdev( mu, s ): logistic distribution standard deviation.
variance( mu, s ): logistic distribution variance.

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

Logistic( [mu, s] ): logistic distribution constructor.

var Logistic = require( '@stdlib/stats-base-dists-logistic' ).Logistic;

var dist = new Logistic( 2.0, 4.0 );

var y = dist.pdf( 2.0 );
// returns 0.0625

Examples

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

console.log( objectKeys( logistic ) );
