Spatial causal inference in the presence of preferential sampling to study the impacts of marine protected areas
Dongjae Son, Brian J. Reich, Erin M. Schliep +2
Marine Protected Areas (MPAs) have been established globally to conserve marine resources. Given their maintenance costs and impact on commercial fishing, it is critical to evaluat…
Doubly protected estimation for survival outcomes utilizing external controls for randomized clinical trials
Chenyin Gao, Shu Yang, Mingyang Shan +3
Censored survival data are common in clinical trials, but small control groups can pose challenges, particularly in rare diseases or where balanced randomization is impractical. Re…
Enhancing Statistical Validity and Power in Hybrid Controlled Trials: A Randomization Inference Approach with Conformal Selective Borrowing
Ke Zhu, Shu Yang, Xiaofei Wang
External controls from historical trials or observational data can augment randomized controlled trials when large-scale randomization is impractical or unethical, such as in drug…
Off-Policy Evaluation with Irregularly-Spaced, Outcome-Dependent Observation Times
Xin Chen, Wenbin Lu, Shu Yang +1
While the classic off-policy evaluation (OPE) literature commonly assumes decision time points to be evenly spaced for simplicity, in many real-world scenarios, such as those invol…
Improve Sensitivity Analysis Synthesizing Randomized Clinical Trials With Limited Overlap
Kuan Jiang, Wenjie Hu, Shu Yang +2
Randomized clinical trials are the gold standard when estimating the average treatment effect. However, they are usually not a random sample from the real-world population because…
Bayesian Structured Mediation Analysis With Unobserved Confounders
Yuliang Xu, Shu Yang, Jian Kang
We explore methods to reduce the impact of unobserved confounders on the causal mediation analysis of high-dimensional mediators with spatially smooth structures, such as brain ima…
Inference for Optimal Linear Treatment Regimes in Personalized Decision-making
Yuwen Cheng, Shu Yang
Personalized decision-making, tailored to individual characteristics, is gaining significant attention. The optimal treatment regime aims to provide the best-expected outcome in th…
Two-phase rejective sampling and its asymptotic properties
Shu Yang, Peng Ding
Rejective sampling improves design and estimation efficiency of single-phase sampling when auxiliary information in a finite population is available. When such auxiliary informatio…
Mixed Matrix Completion in Complex Survey Sampling under Heterogeneous Missingness
Xiaojun Mao, Hengfang Wang, Zhonglei Wang +1
Modern surveys with large sample sizes and growing mixed-type questionnaires require robust and scalable analysis methods. In this work, we consider recovering a mixed dataframe ma…
Continuous-time structural failure time model for intermittent treatment
Guanbo Wang, Siyi Liu, Shu Yang
The intermittent intake of treatment is commonly seen in patients with chronic disease. For example, patients with atrial fibrillation may need to discontinue the oral anticoagulan…
