Here we present a Bayesian hierarchical model to infer the main features that explain score differences in rugby matches of the English Premiership Rugby 2020/2021 season. The main result is that, indeed, effort (seen as a ratio between the number of tries and the scoring kick…

TLDR
A psychometric model based on a multidimensional nominal model for response style that also simultaneously accommodates a respondent-level anchoring tendency is proposed, and results support attending to both anchoring and midpoint response style as ways of assessing respondent engagement.

Abstract Amid much recent interest we discuss a Variance Gamma model for Rugby Union matches (applications to other sports are possible). Our model emerges as a special case of the recently
