Contributing to ArviZ#


Welcome to the ArviZ project! If you’re reading this guide, that probably means you’d like to get involved and start contributing to the project. ArviZ is a multi-language open-source project that provides tools for exploratory analysis of Bayesian models. The package includes functions for posterior analysis, data storage, sample diagnostics, model checking, and comparison.

As a scientific, community-driven, open-source software project, we welcome contributions from interested individuals or groups. The guidelines specified in this document can help new contributors make their contributions compliant with the conventions of the ArviZ python library, and maximize the probability of such contributions being merged as quickly and as efficiently as possible.

All kinds of contributions to ArviZ, either on its codebase, its documentation, or its community are valuable and we appreciate your help. We constantly encourage non-code contributors to become core contributors and participate in ArviZ governance.
