Mode
Triangular distribution mode.
The mode for a triangular random variable with lower limit a
, upper limit b
, and mode c
is
Usage
var mode = require( '@stdlib/stats/base/dists/triangular/mode' );
mode( a, b, c )
Returns the mode of a triangular distribution with parameters a
(minimum support), b
(maximum support), and c
(mode).
var v = mode( 0.0, 1.0, 0.8 );
// returns 0.8
v = mode( 4.0, 12.0, 5.0 );
// returns 5.0
v = mode( 2.0, 8.0, 5.0 );
// returns 5.0
If provided NaN
as any argument, the function returns NaN
.
var v = mode( NaN, 4.0, 2.0 );
// returns NaN
v = mode( 0.0, NaN, 2.0 );
// returns NaN
v = mode( 0.0, 4.0, NaN );
// returns NaN
If provided parameters not satisfying a <= c <= b
, the function returns NaN
.
var y = mode( 1.0, 0.0, 1.5 );
// returns NaN
y = mode( 0.0, 1.0, -1.0 );
// returns NaN
y = mode( 0.0, -1.0, 0.5 );
// returns NaN
Examples
var randu = require( '@stdlib/random/base/randu' );
var mode = require( '@stdlib/stats/base/dists/triangular/mode' );
var a;
var b;
var c;
var v;
var i;
for ( i = 0; i < 10; i++ ) {
a = ( randu()*10.0 );
b = ( randu()*10.0 ) + a;
c = ( randu()*( b-a ) ) + a;
v = mode( a, b, c );
console.log( 'a: %d, b: %d, c: %d, mode(X;a,b,c): %d', a.toFixed( 4 ), b.toFixed( 4 ), c.toFixed( 4 ), v.toFixed( 4 ) );
