Mode

Bradford distribution mode.

The mode for a Bradford random variable is

where c is the shape parameter.

Installation

npm install @stdlib/stats-base-dists-bradford-mode

Usage

var mode = require( '@stdlib/stats-base-dists-bradford-mode' );

mode( c )

Returns the mode of a Bradford distribution with shape parameter c.

var v = mode( 0.1 );
// returns 0.0

v = mode( 10.0 );
// returns 0.0

If provided a shape parameter c <= 0, the function returns NaN.

var v = mode( 0.0 );
// returns NaN

v = mode( -1.5 );
// returns NaN

Examples

var uniform = require( '@stdlib/random-array-uniform' );
var logEachMap = require( '@stdlib/console-log-each-map' );
var mode = require( '@stdlib/stats-base-dists-bradford-mode' );

var opts = {
    'dtype': 'float64'
};
var c = uniform( 10, 0.1, 10.0, opts );

logEachMap( 'c: %0.4f, mode(X;c): %0.4f', c, mode );

C APIs

Usage

#include "stdlib/stats/base/dists/bradford/mode.h"

stdlib_base_dists_bradford_mode( c )

Returns the mode of a Bradford distribution.

double out = stdlib_base_dists_bradford_mode( 0.5 );
// returns 0.0

The function accepts the following arguments:

• c: [in] double shape parameter.

double stdlib_base_dists_bradford_mode( const double c );

Examples

#include "stdlib/stats/base/dists/bradford/mode.h"
#include <stdlib.h>
#include <stdio.h>

static double random_uniform( const double min, const double max ) {
    double v = (double)rand() / ( (double)RAND_MAX + 1.0 );
    return min + ( v*(max-min) );
}

int main( void ) {
    double c;
    double y;
    int i;

    for ( i = 0; i < 10; i++ ) {
        c = random_uniform( 0.01, 10.0 );
        y = stdlib_base_dists_bradford_mode( c );
        printf( "c: %lf, mode(X;c): %lf\n", c, y );
    }
}
