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 ) );
