RCD is a Python library for Recursive Causal Discovery.
This package provides efficient implementations of algorithms that recursively learn a causal graph from observational data.
RCD focuses on user-friendliness with a well-documented and uniform interface. Moreover, its modular design allows for the integration and expansion of other algorithms and models within the package.
If you use RCD in a scientific publication, we would appreciate citations to the following paper:

The package is available on PyPI and can be installed using pip:
pip install rcdThe following snipped creates a random directed acyclic graph (DAG) and generates Gaussian data from it. Then, it uses one of the algorithms provided in our package, RSL-D, to learn the skeleton of the DAG from the data. Finally, it compares the learned skeleton to the true skeleton and computes the F1 score based on the edges.
