Functions for sampling random variables from probability distributions. Uses the same function names as R.
npm install --save probability-distributions
var PD = require("probability-distributions");

Binomial distribution
Beta distribution
Cauchy distribution
Chi-Squared distribution
Exponential distribution
F distribution
Gamma distribution
Laplace distribution
Log Normal distribution
Negative Binomial distribution
Normal (Gaussian) distribution
Poisson distribution (not recommended for lambda > 100)
Sample (shuffle an array, or select items using optional array of weights)
Uniform distribution (with entropy option for standard uniform)
Uniform limited to whole numbers
Words (generate random words from a library of characters)
Visualization (show the values of a random variable in an animated loop)
This package contains additional distributions marked as "experimental". Use these with extreme caution.
