Directed Cyclic Graphs for Causal Discovery

Directed cyclic graphs are a powerful tool for causal discovery in longitudinal observational data. They allow for the simultaneous discovery of time-lagged and instantaneous causality, which is crucial in understanding complex systems where variables may influence each other over time. The framework developed for this purpose is based on common causal discovery assumptions and incorporates instrumental variables, which are often available in longitudinal data. This approach is unique in its ability to achieve causal identifiability in directed graphs with cyclic patterns, a significant advancement in the field. The structural learning process is fully Bayesian, providing a robust statistical foundation for the model. Extensive simulations and real-world applications, such as the Women's Interagency HIV Study, have demonstrated the model's effectiveness and superiority over existing methods.
