Complier General Causal Effect in Randomized Controlled Trials with One-Sided Noncompliance
Yin Tang, Yanyuan Ma, Jiwei Zhao
A randomized controlled trial (RCT) is widely regarded as the gold standard for assessing the causal effect of a treatment or intervention, assuming perfect implementation. In prac…
Unsupervised Domain Adaptation for Binary Classification with an Unobservable Source Subpopulation
Chao Ying, Jun Jin, Haotian Zhang +4
We study an unsupervised domain adaptation problem where the source domain consists of subpopulations defined by the binary label and a binary background (or environment) .…
Borrowing Information from an Unidentifiable Model: Guaranteed Efficiency Gain with a Dichotomized Outcome in the External Data
Lu Wang, Yanyuan Ma, Jiwei Zhao
In the era of big data, the increasing availability of diverse data sources has driven interest in analytical approaches that integrate information across sources to enhance statis…
Efficient Inference under Label Shift in Unsupervised Domain Adaptation
Seong-ho Lee, Yanyuan Ma, Jiwei Zhao
In many real-world applications, researchers aim to deploy models trained in a source domain to a target domain, where obtaining labeled data is often expensive, time-consuming, or…
