Rayleigh

Rayleigh distribution.

Usage

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

rayleigh

Rayleigh distribution.

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

The namespace contains the following distribution functions:

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

The namespace contains the following functions for calculating distribution properties:

entropy( sigma ): Rayleigh distribution differential entropy.
kurtosis( sigma ): Rayleigh distribution excess kurtosis.
mean( sigma ): Rayleigh distribution expected value.
median( sigma ): Rayleigh distribution median.
mode( sigma ): Rayleigh distribution mode.
skewness( sigma ): Rayleigh distribution skewness.
variance( sigma ): Rayleigh distribution variance.

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

Rayleigh( [sigma] ): Rayleigh distribution constructor.

var Rayleigh = require( '@stdlib/stats/base/dists/rayleigh' ).Rayleigh;

var dist = new Rayleigh( 2.0 );

var y = dist.pdf( 0.8 );
// returns ~0.185

Examples

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

console.log( objectKeys( rayleigh ) );
