摘要

Causal effect evaluation and causal network learning are two main research areas in causal inference. For causal effect evaluation; we review the two problems of confounders and surrogates. The Yule-Simpson paradox is the idea that the association between two variables may be changed dramatically due to ignoring confounders. We review criteria for confounders and methods ofadjustment for observed and unobserved confounders. The surrogate paradox occurs when a treatment has a positive causal effect ona surrogate endpoint, which, in turn, has a positive causal effect on a true endpoint, but thetreatmentmayhaveanegativecausaleffectonthetrueendpoint. Someof the existing criteria for surrogates are subject to the surrogate paradox, and we review criteria for consistent surrogates to avoid the surrogate paradox. Causal networks are used to depict the causal relationships among multiple variables. Rather than discovering a global causal network, researchers are ofteninterested indiscoveringthe causes and effects ofa givenvariable. We review some algorithms for local structure learning of causal networks centering around a given variable.
