Accurately estimating personalized treatment effects within a study site
(e.g., a hospital) has been challenging due to limited sample size.
Furthermore, privacy considerations and lack of resources prevent a site from
leveraging subject-level data from other sites. We propose a tree-based model
averaging approach to improve the estimation accuracy of conditional average
treatment effects (CATE) at a target site by leveraging models derived from
other potentially heterogeneous sites, without them sharing subject-level data.
To our best knowledge, there is no …
