    Median

    NPM version Build Status Coverage Status

    Arcsine distribution median.

    The median for an arcsine random variable is

    Median for an arcsine distribution.

    where a is the minimum support and b is the maximum support.

    Installation

    npm install @stdlib/stats-base-dists-arcsine-median

    Usage

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

    median( a, b )

    Returns the median of an arcsine distribution with parameters a (minimum support) and b (maximum support).

    var v = median( 0.0, 1.0 );
    // returns 0.5
    
    v = median( 4.0, 12.0 );
    // returns 8.0
    
    v = median( 2.0, 8.0 );
    // returns 5.0

    If provided NaN as any argument, the function returns NaN.

    var v = median( NaN, 2.0 );
    // returns NaN
    
    v = median( 2.0, NaN );
    // returns NaN

    If provided a >= b, the function returns NaN.

    var y = median( 3.0, 2.0 );
    // returns NaN
    
    y = median( 3.0, 3.0 );
    // returns NaN

    Examples

    var randu = require( '@stdlib/random-base-randu' );
    var median = require( '@stdlib/stats-base-dists-arcsine-median' );
    
    var a;
    var b;
    var v;
    var i;
    
    for ( i = 0; i < 10; i++ ) {
        a = ( randu()*10.0 );
        b = ( randu()*10.0 ) + a;
        v = median( a, b );
        console.log( 'a: %d, b: %d, Median(X;a,b): %d', a.toFixed( 4 ), b.toFixed( 4 ), v.toFixed( 4 ) );
    }
