Median
The median for a Bernoulli random variable is
where p is the success probability.
Usage
var median = require( '@stdlib/stats/base/dists/bernoulli/median' );
median( p )
Returns the median of a Bernoulli distribution with success probability p.
var v = median( 0.1 );
// returns 0
v = median( 0.8 );
// returns 1
If provided a success probability p outside of [0,1], the function returns NaN.
var v = median( NaN );
// returns NaN
v = median( 1.5 );
// returns NaN
v = median( -1.0 );
// returns NaN
Examples
var randu = require( '@stdlib/random/base/randu' );
var round = require( '@stdlib/math/base/special/round' );
var median = require( '@stdlib/stats/base/dists/bernoulli/median' );
var v;
var i;
var p;
for ( i = 0; i < 10; i++ ) {
p = randu();
v = median( p );
console.log( 'p: %d, Median(X;p): %d', p.toFixed( 4 ), v.toFixed( 4 ) );
