Median
The median for a uniform random variable is
where a is the minimum support and b the maximum support of the distribution.
Usage
var median = require( '@stdlib/stats/base/dists/uniform/median' );
median( a, b )
Returns the median of a uniform 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/uniform/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 ) );
