    Cumulative Distribution Function

    NPM version Build Status Coverage Status dependencies

    Degenerate distribution cumulative distribution function.

    The cumulative distribution function for a degenerate random variable is

    Cumulative distribution function for a degenerate distribution.

    where µ is the constant value of the distribution.

    Installation

    npm install @stdlib/stats-base-dists-degenerate-cdf

    Usage

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

    cdf( x, mu )

    Evaluates the CDF of a degenerate distribution centered at mu.

    var y = cdf( 2.0, 8.0 );
    // returns 0.0
    
    y = cdf( 8.0, 8.0 );
    // returns 1.0
    
    y = cdf( 10.0, 8.0 );
    // returns 1.0

    cdf.factory( mu )

    Returns a function for evaluating the cumulative distribution function of a degenerate distribution centered at mu.

    var mycdf = cdf.factory( 10.0 );
    
    var y = mycdf( 10.0 );
    // returns 1.0
    
    y = mycdf( 8.0 );
    // returns 0.0

    Examples

    var randu = require( '@stdlib/random-base-randu' );
    var round = require( '@stdlib/math-base-special-round' );
    var cdf = require( '@stdlib/stats-base-dists-degenerate-cdf' );
    
    var mu;
    var x;
    var y;
    var i;
    
    for ( i = 0; i < 100; i++ ) {
        x = round( randu()*10.0 );
        mu = round( randu()*10.0 );
        y = cdf( x, mu );
        console.log( 'x: %d, µ: %d, F(x;µ): %d', x, mu, y );
    }
