报告摘要:

In recent years, substantial research effort has been devoted to developing methodology for high dimensional mediation analysis to identify variables from a high-dimensional set to explain the causal mechanism. Traditional screening approaches are often applied, while the linear structural equation model structure of the mediation problem is not well accounted for. We propose a new marginal screening procedure, termed Marginal Sobel Screening (MSS), for high dimensional mediation analysis that takes into account the mediation model structure. We establish sample level properties and population properties to ensure the sure screening property for MSS. MSS is shown via simulation to perform better than benchmark approaches and is applied to the Coronary Artery Risk Development inYoung Adults (CARDIA) Study to examine the mediation effect of ultra-high dimensional DNA methylation markers.
