    NPM version Build Status Coverage Status

    Kumaraswamy's double bounded distribution.

    Installation

    npm install @stdlib/stats-base-dists-kumaraswamy

    Usage

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

    kumaraswamy

    Kumaraswamy's double bounded distribution.

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

    The namespace contains the following distribution functions:

    • cdf( x, a, b ): Kumaraswamy's double bounded distribution cumulative distribution function.
    • logcdf( x, a, b ): evaluate the natural logarithm of the cumulative distribution function for a Kumaraswamy's double bounded distribution.
    • logpdf( x, a, b ): evaluate the natural logarithm of the probability density function for a Kumaraswamy's double bounded distribution.
    • pdf( x, a, b ): Kumaraswamy's double bounded distribution probability density function.
    • quantile( p, a, b ): Kumaraswamy's double bounded distribution quantile function.

    The namespace contains the following functions for calculating distribution properties:

    • kurtosis( a, b ): Kumaraswamy's double bounded distribution excess kurtosis.
    • mean( a, b ): Kumaraswamy's double bounded distribution expected value.
    • median( a, b ): Kumaraswamy's double bounded distribution median.
    • mode( a, b ): Kumaraswamy's double bounded distribution mode.
    • skewness( a, b ): Kumaraswamy's double bounded distribution skewness.
    • stdev( a, b ): Kumaraswamy's double bounded distribution standard deviation.
    • variance( a, b ): Kumaraswamy's double bounded distribution variance.

    The namespace contains a constructor function for creating a Kumaraswamy's double bounded distribution object.

    var Kumaraswamy = require( '@stdlib/stats-base-dists-kumaraswamy' ).Kumaraswamy;
    
    var dist = new Kumaraswamy( 2.0, 4.0 );
    
    var y = dist.logpdf( 0.8 );
    // returns ~-1.209

    Examples

    var objectKeys = require( '@stdlib/utils-keys' );
    var kumaraswamy = require( '@stdlib/stats-base-dists-kumaraswamy' );
    
    console.log( objectKeys( kumaraswamy ) );

    Notice

    This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
