statdists.js

This is a super tiny library that currently simulates the functionality of R for generating random variables (r<dist>) and also calculating their density (d<dist>). It also includes a few vectorized math functions that help in translating code from something like numpy or dplyr to javascript.

In the future this will recreate all of the distributions in R, but currently it does not calculate CDFs.

Relies on the library d3-random because I'm too lazy to code the CDF of the normal to generate my own normal samples.

Installing

The library is on NPM and is bundled in the UMD format.

npm install --save statdists

import {rnorm, runif} from 'statdists';

const someNormals = rnorm(10, 6, 2);
console.log(someNormals)
