Distributions provides low-level primitives for collapsed Gibbs sampling in Python and C++ including:

• special numerical functions,
• samplers and density functions from a variety of distributions,
• conjugate component models (e.g., gamma-Poisson, normal-inverse-chi-squared),
• clustering models (e.g., CRP, Pitman-Yor), and
• efficient wrappers for mixture models.

Distributions powered a machine-learning-as-a-service for Prior Knowledge Inc., and now powers machine learning infrastructure at Salesforce.com.

For python-only support (no C++) you can install with pip:

pip install distributions

For help with other builds, see the installation documentation.
