In-Sample Evaluation of Subgroups Identified by Generic Machine Learning
Shuoxun Xu, Xinzhou Guo
When a subgroup is identified from the data, it must be evaluated in a replicable way. The usual in-sample approach, which evaluates the post-hoc identified subgroup as predefined,…

Optimal Inference of the Mean Outcome under Optimal Treatment Regime
Shuoxun Xu, Xinzhou Guo
When an optimal treatment regime (OTR) is considered, we need to evaluate the OTR in a valid and efficient way. The classical inference applied to the mean outcome under OTR, assum…
