Reachability-Based Primitives for Graphical Causal Inference R package ciflyr version 0.1.2 Provides a framework for specifying and running flexible linear-time reachability-based algorithms for graphical causal inference. Rule tables are used to encode and customize the reachability algorithm to typical causal and probabilistic reasoning tasks such as finding d-connected nodes or more advanced applications.
