Hola! 👋 right now the gem got an update that introduced a breaking change in master where the Outermost namespace was changed to be ruby_statistics instead of statistics. This change is in master already and released in version 4.0. If you're relying on branch instead of gem version, you can checkout branch 3.x. This branch will be supported but no additional features will be added.
A basic ruby gem that implements some statistical methods, functions and concepts to be used in any ruby environment without depending on any mathematical software like R, Matlab, Octave or similar.
Unit test runs under the following ruby versions:
- Ruby 3.0.
- Ruby 3.1.
- Ruby 3.2.
- Ruby 3.3.
We got the inspiration from the folks at JStat and some interesting lectures about Keystroke dynamics.

Add this line to your application's Gemfile:
gem 'ruby-statistics'And then execute:
$ bundle
Or install it yourself as:
$ gem install ruby-statistics
just require the ruby-statistics gem in order to load it. If you don't have defined the Distribution namespace, the gem will assign an alias, reducing the number of namespaces needed to use a class.
Right now you can load:
- The whole statistics gem.
require 'ruby-statistics' - A namespace.
require 'ruby-statistics/distribution' - A class.
require 'ruby-statistics/distribution/normal'
Feel free to use the one that is more convenient to you.
require 'ruby-statistics'
poisson = Distribution::Poisson.new(l) # Using Distribution alias.
normal = RubyStatistics::Distribution::StandardNormal.new # Using all namespaces.You can find a bit more detailed documentation of all available distributions, tests and functions in the Documentation Index
After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
