randgen

Node.js package for generating different kinds of random numbers: Uniform, Normal/Gaussian, Poisson, Chi-squared, Cauchy.

Installation:

npm install randgen

Features:

• Supported distributions: Uniform, Normal, Poisson, Chi-Square, Cauchy
• Vector versions of all supported distributions

Usage:

Generate Gaussian random numbers:

num = rnorm();     // standard normal
num = rnorm(2, 5); // normal with mean 2 and standard deviation of 5

Chi-Squared:

num = rchisq(4);   // 4 degrees of freedom

Others: runif, rpoisson, rcauchy

You can also generate vectors of random numbers:

nums = rvnorm(100); // generate 100 standard normal values

Others: rvunif, rvchisq, rvpoisson, rvcauchy

It also includes a handy histogram() function to convert an array of numbers into a set of bins:

bins = histogram(data);     // defaults to 10 bins
bins = histogram(data, 20); // 20 bins
