# Distributions
[](https://travis-ci.org/posterior/distributions) [](https://pypi.python.org/pypi/distributions) [](https://zenodo.org/badge/latestdoi/29212688)
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.
## Installation
For python-only support (no C++) you can install with pip:
pip install distributions
For help with other builds, see [the installation documentation](http://distributions.readthedocs.org/en/latest/installation.html).

A note on package security
PyPI is a repository for distributing packages, not a service for auditing them. While third-party security researchers and our staff do their best to detect and remove malicious packages, PyPI cannot guarantee the quality, security or suitability of any given package.
