The Covariate-Assisted Bayesian Intransitive Bradley-Terry Model via Combinatorial Hodge Theory
Hisaya Okahara, Tomoyuki Nakagawa, Shonosuke Sugasawa
Pairwise comparison data are widely used to recover latent rankings, yet the models in dominant use assume stochastic transitivity. When preferences are in fact intransitive, a sin…

Modeling asymmetry in multi-way contingency tables with ordinal categories via f-divergence
Hisaya Okahara, Kouji Tahata
This study introduces a novel model that effectively captures asymmetric structures in multivariate contingency tables with ordinal categories. Leveraging the principle of maximum…

A generalized ordinal quasi-symmetry model and its separability for analyzing multi-way tables
Hisaya Okahara, Kouji Tahata
This paper addresses the challenge of modeling multi-way contingency tables for matched set data with ordinal categories. Although the complete symmetry and marginal homogeneity mo…
