Logistic

Logistic distribution.

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 ) );
