benedictleejh / simple-random

Simple random number generator gem for Ruby (based on C# code by John D. Cook).

simple-random¶ ↑

Generate random numbers sampled from the following distributions:

• Beta

• Cauchy

• Chi square

• Dirichlet

• Exponential

• Gamma

• Inverse gamma

• Laplace (double exponential)

• Normal

• Student t

• Uniform

• Weibull

Based on John D. Cook’s SimpleRNG C# library.

Note on Patches/Pull Requests¶ ↑

• Fork the project.

• Make your feature addition or bug fix.

• Add tests for it. This is important so I don’t break it in a future version unintentionally.

• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

• Send me a pull request. Bonus points for topic branches.
