存在潜变量和选择偏差时的因果推理

Causal Inference in the Presence of Latent Variables and Selection Bias

Carnegie Mellon University(卡内基梅隆大学)

Peter L. Spirtes, Christopher Meek, Thomas S. Richardson

摘要:

我们发现,有一个通用的,翔实的和可靠的程序发现因果关系时,所有的调查人员知道,潜在变量和选择偏差可能在工作中。给定关于测量变量之间的条件独立性和依赖关系的信息,即使潜在变量和选择偏差可能存在,也有足够的条件可靠地得出从一个变量到另一个变量存在因果路径的结论,并且当不存在这种因果路径时,也有足够的条件可靠地得出结论。

英文摘要:

We show that there is a general, informative and reliable procedure for discovering causal relations when, for all the investigator knows, both latent variables and selection bias may be at work. Given information about conditional independence and dependence relations between measured variables, even when latent variables and selection bias may be present, there are sufficient conditions for reliably concluding that there is a causal path from one variable to another, and sufficient conditions for reliably concluding when no such causal path exists.
