报告题目:A negative control method for removing confounding

报 告 人:苗旺博士 北京大学

报告时间:20191021日下午1400-1500

报告地点:数学楼第二报告厅

报告摘要:

Confounding often arises in observational studies, and it may jeopardize causal inference and lead to biased results. In this talk, I will present a mitigation method we recently developed, which incorporated auxiliary variables called negative controls to eliminate the confounding bias. We show that under certain completeness conditions, the actual causal effect is identified with both a negative control exposure and a negative control outcome. I will also illustrate with several examples including a time-series air pollution study.
