Conditional Predictive Inference for General Structured Data with Group Symmetries
Yichen Shen, Mengxin Yu
We study distribution-free predictive inference for data with group symmetries, aiming to establish near-conditional coverage guarantees beyond exchangeability for structured data.…

Test-negative designs with various reasons for testing: statistical bias and solution
Mengxin Yu, Tom Hongyi Liu, Kendrick Qijun Li +5
Test-negative designs are widely used for post-market evaluation of vaccine effectiveness, particularly in cases when randomized trials are not feasible. Differing from classical t…

Conformal causal inference for cluster randomized trials: model-robust inference without asymptotic approximations
Bingkai Wang, Fan Li, Mengxin Yu
Traditional statistical inference in cluster randomized trials typically invokes the asymptotic theory that requires the number of clusters to approach infinity. In this article, w…
