ArviZ
Exploratory analysis of Bayesian models
ArviZ is a Python package for exploratory analysis of Bayesian models. It serves as a backend-agnostic tool for diagnosing and visualizing Bayesian inference.
Key Features#
Interoperability
Integrates with all major probabilistic programming libraries: PyMC, CmdStanPy, PyStan, Pyro, NumPyro, and emcee.
Large Suite of Visualizations
Provides over 25 plotting functions for all parts of Bayesian workflow: visualizing distributions, diagnostics, and model checking. See the gallery for examples.
State of the Art Diagnostics
Latest published diagnostics and statistics are implemented, tested and distributed with ArviZ.
Flexible Model Comparison
Includes functions for comparing models with information criteria, and cross validation (both approximate and brute force).
Built for Collaboration
Designed for flexible cross-language serialization using netCDF or Zarr formats. ArviZ also has a Julia version that uses the same data schema.
Labeled Data
Builds on top of xarray to work with labeled dimensions and coordinates.
