Fréchet

Fréchet distribution.

Usage

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

frechet

Fréchet distribution.

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

The namespace contains the following distribution functions:

• cdf( x, alpha, s, m ): Fréchet distribution cumulative distribution function.
• logcdf( x, alpha, s, m ): Fréchet distribution logarithm of cumulative distribution function.
• logpdf( x, alpha, s, m ): Fréchet distribution logarithm of probability density function.
• pdf( x, alpha, s, m ): Fréchet distribution probability density function.
• quantile( p, alpha, s, m ): Fréchet distribution quantile function.

The namespace contains the following functions for calculating distribution properties:

• entropy( alpha, s, m ): Fréchet distribution differential entropy.
• kurtosis( alpha, s, m ): Fréchet distribution kurtosis.
• mean( alpha, s, m ): Fréchet distribution expected value.
• median( alpha, s, m ): Fréchet distribution median.
• mode( alpha, s, m ): Fréchet distribution mode.
• skewness( alpha, s, m ): Fréchet distribution skewness.
• stdev( alpha, s, m ): Fréchet distribution standard deviation.
• variance( alpha, s, m ): Fréchet distribution variance.

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

• Frechet( [alpha, s, m] ): Fréchet distribution constructor.

var Frechet = require( '@stdlib/stats/base/dists/frechet' ).Frechet;

var dist = new Frechet( 2.0, 4.0, 3.0 );

var y = dist.pdf( 5.5 );
// returns ~0.158

Examples

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

console.log( objectKeys( frechet ) );
