cegpy

Cegpy (/segpaɪ/) is a Python package for working with Chain Event Graphs. It supports learning the graphical structure of a Chain Event Graph from data, encoding of parametric and structural priors, estimating its parameters, and performing inference.

It is built on top of the Python network modelling package NetworkX.

Documentation

Documentation is hosted on read the docs.

We have also written a paper to explain the statistical methods and algorithms included in the package; ARXIV - cegpy: Modelling with Chain Event Graphs in Python.

Quickstart

If you'd like to get started using the packages, the best place to start is the quick-start documentation.

Example Binder

Use cases have been demonstrated in a binder.
