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!
Logistic distribution.
To use in Observable,
logistic = require( 'https://cdn.jsdelivr.net/gh/stdlib-js/stats-base-dists-logistic@umd/browser.js' )To vendor stdlib functionality and avoid installing dependency trees for Node.js, you can use the UMD server build:
var logistic = require( 'path/to/vendor/umd/stats-base-dists-logistic/index.js' )To include the bundle in a webpage,
<script type="text/javascript" src="https://cdn.jsdelivr.net/gh/stdlib-js/stats-base-dists-logistic@umd/browser.js"></script>If no recognized module system is present, access bundle contents via the global scope:
<script type="text/javascript">
(function () {
window.logistic;
})();
</script>Logistic distribution.
var dist = logistic;
// returns {...}The namespace contains the following distribution functions:
cdf( x, mu, s ): logistic distribution cumulative distribution function.logcdf( x, mu, s ): logistic distribution logarithm of cumulative distribution function.logpdf( x, mu, s ): logistic distribution logarithm of probability density function (PDF).mgf( t, mu, s ): logistic distribution moment-generating function (MGF).pdf( x, mu, s ): logistic distribution probability density function (PDF).quantile( p, mu, s ): logistic distribution quantile function.
The namespace contains the following functions for calculating distribution properties:
entropy( mu, s ): logistic distribution differential entropy.kurtosis( mu, s ): logistic distribution excess kurtosis.mean( mu, s ): logistic distribution expected value.median( mu, s ): logistic distribution median.mode( mu, s ): logistic distribution mode.skewness( mu, s ): logistic distribution skewness.stdev( mu, s ): logistic distribution standard deviation.variance( mu, s ): logistic distribution variance.
The namespace contains a constructor function for creating a logistic distribution object.
Logistic( [mu, s] ): logistic distribution constructor.
var Logistic = require( '@stdlib/stats-base-dists-logistic' ).Logistic;
var dist = new Logistic( 2.0, 4.0 );
var y = dist.pdf( 2.0 );
// returns 0.0625<!DOCTYPE html>
