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 ) );
