Mode
Exponential distribution mode.
The mode for an exponential random variable with rate parameter λ
is
Usage
var mode = require( '@stdlib/stats/base/dists/exponential/mode' );
mode( lambda )
Returns the mode of an exponential distribution with rate parameter lambda
.
var v = mode( 9.0 );
// returns 0.0
v = mode( 0.5 );
// returns 0.0
If provided lambda < 0
, the function returns NaN
.
var v = mode( -1.0 );
// returns NaN
Examples
var randu = require( '@stdlib/random/base/randu' );
var round = require( '@stdlib/math/base/special/round' );
var mode = require( '@stdlib/stats/base/dists/exponential/mode' );
var lambda;
var v;
var i;
for ( i = 0; i < 10; i++ ) {
lambda = randu() * 20.0;
v = mode( lambda );
console.log( 'λ: %d, mode(X;λ): %d', lambda.toFixed( 4 ), v.toFixed( 4 ) );
