Fisher's F

Fisher's F distribution.

Usage

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

f

Fisher's F distribution.

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

The namespace contains the following distribution functions:

• cdf( x, d1, d2 ): F distribution cumulative distribution function.
• pdf( x, d1, d2 ): F distribution probability density function (PDF).
• quantile( p, d1, d2 ): F distribution quantile function.

The namespace contains the following functions for calculating distribution properties:

• entropy( d1, d2 ): F distribution differential entropy.
• kurtosis( d1, d2 ): F distribution excess kurtosis.
• mean( d1, d2 ): F distribution expected value.
• mode( d1, d2 ): F distribution mode.
• skewness( d1, d2 ): F distribution skewness.
• stdev( d1, d2 ): F distribution standard deviation.
• variance( d1, d2 ): F distribution variance.

The namespace contains a constructor function for creating a Fisher's F distribution object.

• F( [d1, d2] ): F distribution constructor.

var F = require( '@stdlib/stats/base/dists/f' ).F;

var dist = new F( 2.0, 4.0 );

var y = dist.cdf( 0.5 );
// returns ~0.36

Examples

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

console.log( objectKeys( f ) );
