We consider the problem of structure learning for bow-free acyclic path diagrams (BAPs). BAPs can be viewed as a generalization of linear Gaussian DAG models that allow for certain hidden variables. We present a first method for this problem using a greedy score-based search algorithm. We also investigate some distributional equivalence properties of BAPs which are used in an algorithmic approach to compute (nearly) equivalent model structures, allowing to infer lower bounds of causal effects. The application of our method to some datasets reveals that BAP models can represent the data much better than DAG models in these cases Show more
