This paper describes the R add-on package BradleyTerry, which facilitates the specification and fitting of Bradley-Terry logit models to pair-comparison data. Included are the standard "unstructured" Bradley-Terry model, structured versions in which the parameters are related through a linear ...
这件事在 BT model 的历史上被大量研究过,文献中称为 Bradley-Terry regression。延续这一思路,我们的文章在 LLM alignment 这个特殊场景下,给出了使用 Siamese MLP 结构实现 BT regression 的收敛性证明。 1.2 Bradley-Terry背后的假设 当我们谈论 Preference 是...
This is a short overview of the R add-on package BradleyTerry2, which facilitates the specification and fitting of Bradley-Terry logit, probit or cauchit models to pair-comparison data. Included are the standard 'unstructured' Bradley-Terry model, structured versions in which the parameters are ...

Bradley-Terry Model The Bradley-Terry Model is useful when comparing the results of a bunch of pairings to see what item is most relevant or best choice. It's also used a bunch to determine the best team to bet on. I wrote this version because I need to compare the preferred pieces ...
