How PC-based Methods Err: Towards Better Reporting of Assumption Violations and Small Sample Errors
This episode discusses the paper "How PC-based Methods Err," which analyzes systematic failure modes in PC algorithms used for finding causal links. Hosts detail three types of errors—orientation conflicts, incoherencies, and graph-type mismatches—and introduce a computationally cheap 'Coherency Score' to better quantify and report these limitations.
