Regression-based estimation of heterogeneous treatment effects when extending inferences from a randomized trial to a target population
随机试验推断向目标人群扩展时的异质性处理效应回归估计
Methods for extending -- generalizing or transporting -- inferences from a randomized trial to a target population involve conditioning on a large set of covariates that is sufficient for rendering the randomized and non-randomized groups exchangeable. Yet, decision-makers are often interested in examining treatment effects in subgroups of the target population defined in terms of only a few discrete covariates. Here, we propose methods for estimating subgroup-specific…
