论文摘要
我们表明，具有隐藏变量的离散定向无环图（DAG）的边际模型在分布上等同于另一个完全可观察到的DAG模型，并且仅当它不会诱导任何非平地不平等约束。
We show that the marginal model for a discrete directed acyclic graph (DAG) with hidden variables is distributionally equivalent to another fully observable DAG model if and only if it does not induce any non-trivial inequality constraints.
