Design-based nested instrumental variable analysis
Zhe Chen, Xinran Li, Michael O. Harhay +1
Two binary instrumental variables (IVs) are nested if individuals who comply under one binary IV also comply under the other. This situation often arises when the two IVs represent…
Nested Instrumental Variables Analysis: Switcher Average Treatment Effect, Identification, Efficient Estimation and Generalizability
Rui Wang, Ying-Qi Zhao, Oliver Dukes +1
Instrumental variables (IVs) are widely used to estimate causal effects from non-randomized data. A canonical example is a randomized trial with noncompliance, in which the randomi…
Simultaneous Heterogeneity and Reduced-rank Learning for Multivariate Response Regression
Jie Wu, Bo Zhang, Daoji Li +1
Heterogeneous data are now ubiquitous in many applications in which correctly identifying the subgroups from a heterogeneous population is critical. Although there is an increasing…
One-shot variable-ratio matching with fine balance
Qian Meng, Zhe Chen, Bo Zhang
Variable-ratio matching is a flexible alternative to conventional -to- matching for designing observational studies that emulate a target randomized controlled trial (RCT). T…
