Item response theory (IRT) has become one of the most popular statistical models for psychometrics, a field of study concerned with the theory and techniques of psychological measu…
Determining the Number of Factors in High-dimensional Generalized Latent Factor Models
Yunxiao Chen, Xiaoou Li
As a generalization of the classical linear factor model, generalized latent factor models are useful for analyzing multivariate data of different types, including binary choices a…
Spherical Regression under Mismatch Corruption with Application to Automated Knowledge Translation
Xu Shi, Xiaoou Li, Tianxi Cai
Motivated by a series of applications in data integration, language translation, bioinformatics, and computer vision, we consider spherical regression with two sets of unit-length…
Asymptotically Optimal Sequential Design for Rank Aggregation
Xi Chen, Yunxiao Chen, Xiaoou Li
A sequential design problem for rank aggregation is commonly encountered in psychology, politics, marketing, sports, etc. In this problem, a decision maker is responsible for ranki…
Uniformly Efficient Simulation for Extremes of Gaussian Random Fields
Xiaoou Li, Gongjun Xu
This paper considers the problem of simultaneously estimating rare-event probabilities for a class of Gaussian random fields. A conventional rare-event simulation method is usually…
Optimal Stopping and Worker Selection in Crowdsourcing: an Adaptive Sequential Probability Ratio Test Framework
