Sophisticated fans would argue that the Warriors are better by the transitive property, but could diehard Spurs fans make a legitimate argument that their team is better despite this chain of evidence? We attempt to answer whether the assumption of transitivity in pairwise comparisons should hold by modeling without the assumption.
We propose a novel linear model (CRSP) whose latent bilinear fixed effect allows us to estimate deviations from our transitive model ©. We discuss the mathematical details of the model, including an eigendecomposition that enables an estimate of the latent bilinear fixed effect. We also propose a generalized version of the bilinear fixed effect and demonstrate an application thereof. “ abstract_short = “” event = “Cascadia Symposium on Statistics in Sports” event_url = “https://web.archive.org/web/20180928070719/http://cascadiasports.com/" location = “Vancouver, Canada”
