　　摘要：Many scientific and business challenges, ranging from personalized medicine to customized marketing recommendations, require an understanding of treatment effect heterogeneity. In this talk, based on the causal inference framework, we develop a flexible method for estimating heterogeneous treatment effects. The method can handle binary, continuous, time-to-event, and possibly contaminated outcomes in the same fashion. Furthermore, based on the potential outcome framework and confidence distribution (CD) framework, we propose a confidence measure to quantify the estimation uncertainty in personalized decisions. This measure, with value in [0,1], provides a frequency-based assessment about the decision. It is also shown to match well with the classical assessments of sensitivity and specificity, but without the need to know the true optimal treatment regime. Utility of the development is demonstrated in an adaptive sampling in sequential experiments.
