About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

Mode

NPM version Build Status Coverage Status

Logistic distribution mode.

The mode for a logistic random variable with location μ and scale s > 0 is

Mode for a logistic distribution.

Installation

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

Usage

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

mode( mu, s )

Returns the mode for a logistic distribution with location parameter mu and scale parameter s.

var y = mode( 2.0, 1.0 );
// returns 2.0

y = mode( 0.0, 1.0 );
// returns 0.0

y = mode( -1.0, 4.0 );
// returns -1.0

If provided NaN as any argument, the function returns NaN.

var y = mode( NaN, 1.0 );
// returns NaN

y = mode( 0.0, NaN );
// returns NaN

If provided s <= 0, the function returns NaN.

var y = mode( 0.0, 0.0 );
// returns NaN

y = mode( 0.0, -1.0 );
// returns NaN

Examples

var randu = require( '@stdlib/random-base-randu' );
var mode = require( '@stdlib/stats-base-dists-logistic-mode' );

var mu;
var s;
var y;
var i;

for ( i = 0; i < 10; i++ ) {
    mu = ( randu()*10.0 ) - 5.0;
    s = randu() * 20.0;
    y = mode( mu, s );
    console.log( 'µ: %d, s: %d, mode(X;µ,s): %d', mu.toFixed( 4 ), s.toFixed( 4 ), y.toFixed( 4 ) );
}

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
