Bradley-Terry model under general comparison graphs
Ruijian Han, Yuanhang Luo, Yiming Xu
The Bradley-Terry model is a parametric model for ranking from pairwise comparisons. Existing asymptotic theory for the maximum likelihood estimator (MLE) in regimes where the numb…
Statistical inference for pairwise comparison models
Ruijian Han, Wenlu Tang, Yiming Xu
Pairwise comparison models have been widely used for utility evaluation and rank aggregation across various fields. The increasing scale of modern problems underscores the need to…
A unified analysis of likelihood-based estimators in the Plackett--Luce model
Ruijian Han, Yiming Xu
The Plackett--Luce model has been extensively used for rank aggregation in social choice theory. A central statistical question in this model concerns estimating the utility vector…
Consistency of archetypal analysis
Braxton Osting, Dong Wang, Yiming Xu +1
Archetypal analysis is an unsupervised learning method that uses a convex polytope to summarize multivariate data. For fixed , the method finds a convex polytope with vertic…
