Probability Seminar——Causal Inference in Degenerate Systems: An Impossibility Result
报告人： Yue Wang(University of California, Los Angeles)
地点：Zoom Meeting（875 1061 4993）
Causal relationships among variables are commonly represented via directed acyclic graphs. There are many methods in the literature to quantify the strength of arrows in a causal acyclic graph. These methods, however, have undesirable properties when the causal system represented by a directed acyclic graph is degenerate. In this talk, I will characterize a degenerate causal system using the multiplicity of Markov boundaries. In this case, it is impossible to find an identifiable quantitative measure of causal effects that satisfy a set of natural criteria. To supplement the impossibility result, I will also introduce algorithms to identify degenerate causal systems from observed data. The performance of these algorithms is investigated through synthetic data analysis.
