Mode
The mode for a chi random variable is
for degrees of freedom k >= 1
. For other values of k
, the mode is not defined.
Installation
npm install @stdlib/stats-base-dists-chi-mode
Usage
var mode = require( '@stdlib/stats-base-dists-chi-mode' );
mode( k )
Returns the mode of a chi distribution with degrees of freedom k
.
var v = mode( 9.0 );
// returns ~2.828
v = mode( 1.5 );
// returns ~0.707
If provided k < 1
, the function returns NaN
.
var v = mode( -1.0 );
// returns NaN
v = mode( 0.9 );
// 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-chi-mode' );
var k;
var v;
var i;
for ( i = 0; i < 10; i++ ) {
k = randu() * 20.0;
v = mode( k );
console.log( 'k: %d, mode(X,k): %d', k.toFixed( 4 ), v.toFixed( 4 ) );
}
