I'm interesting in learning about how to rate and rank individuals in a group who only interact/compete in a pairwise fashion (i.e., systems like the ELO rating system for chess).
- Are there are any go-to methods or more accurate and advanced methods out there?
- Are there any R packages that make implementation easy?
- Are there methods that can use auxiliary information as well as the outcome of a match/game?
- Are there methods that can better use the information of winning margin as opposed to dichotomous win/lose?
- What should I be looking for in the literature?
