A Characterization of Interventional Distributions in Semi-Markovian Causal Models
Jin Wen Tian, Changsung Kang, Judea Pearl · eScholarship (California Digital Library) · 2006
We offer a complete characterization of the set of distributions that could be induced by local interventions on variables governed by a causal Bayesian network of unknown structure, in which some of the variables remain unmeasured. We show that such distributions are constrained by a simply formulated set of inequalities, from which bounds can be derived on causal effects that are not directly measured in randomized experiments.
