Asymptotic emergence of statistically supported false causal interpretation under unmeasured confounding
未测混杂下获得统计支持的错误因果解释如何渐近出现
Unmeasured confounding is widely recognized as a limitation of observational causal inference, but its implications for data-driven causal discovery are often understated. We provide an asymptotic characterization of this limitation. When the true causal variable is unobserved but correlated proxy variables are available, increasing sample size while searching for increasingly stable, data-driven causal structures will make associations involving observable proxies become…
