    NPM version Build Status Coverage Status dependencies

    Chi-squared distribution.

    Installation

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

    Usage

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

    chisquare

    Chi-squared distribution.

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

    The namespace contains the following distribution functions:

    • cdf( x, k ): Chi-squared distribution cumulative distribution function.
    • logpdf( x, k ): evaluate the natural logarithm of the probability density function (PDF) for a chi-squared distribution.
    • mgf( t, k ): Chi-squared distribution moment-generating function (MGF).
    • pdf( x, k ): Chi-squared distribution probability density function (PDF).
    • quantile( p, k ): Chi-squared distribution quantile function.

    The namespace contains the following functions for calculating distribution properties:

    The namespace contains a constructor function for creating a Chi-squared distribution object.

    var ChiSquare = require( '@stdlib/stats-base-dists-chisquare' ).ChiSquare;
    
    var dist = new ChiSquare( 4.0 );
    
    var mu = dist.mean;
    // returns 4.0

    Examples

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