A Python library for exploratory analysis, diagnostics, and visualization of Bayesian models.
ArviZ is a Python library for exploratory analysis of Bayesian models. It provides tools for posterior analysis, model checking, comparison, and diagnostics, helping users understand and validate their Bayesian inferences. The library supports data storage and visualization, making it easier to work with probabilistic programming outputs.
Data scientists, statisticians, and researchers who use Bayesian modeling and need tools for model diagnostics, visualization, and comparison. It is particularly useful for those working with probabilistic programming languages like PyMC, Stan, or NumPyro.
ArviZ offers a unified and flexible interface for Bayesian model analysis, with extensive visualization capabilities and modular design. It integrates with multiple probabilistic programming backends, providing consistent diagnostics and comparisons across different modeling frameworks.
Exploratory analysis of Bayesian models with Python
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides a wide range of plotting functions for Bayesian analysis, such as forest plots and trace plots, as shown in the gallery and documentation.
Designed to be modular and flexible, allowing seamless integration with various probabilistic programming languages like PyMC and Stan, as stated in the philosophy.
Supports storing and loading inference data in a standardized format, facilitating reproducibility and data sharing across teams.
Includes tools for checking model convergence, such as rank plots and effective sample size calculations, essential for reliable Bayesian inferences.
Documentation is divided into arviz-base, arviz-stats, and arviz-plots, which can complicate navigation and learning for new users.
Primarily focused on Bayesian modeling, making it less useful for projects outside probabilistic programming or frequentist statistics.
Full functionality requires installing optional packages like 'preview' or separate conda packages, adding setup overhead compared to simpler libraries.
