Chess playing dataset

Description

A tally of wins and losses for games between three chess players: Topalov, Anand, Karpov

Usage

data(chess)

Details

This is a very simple dataset that can be used for illustration of hyper2 idiom.

The players are:

  • Grandmaster Veselin Topalov. FIDE world champion 2005-2006; peak rating 2813

  • Grandmaster Viswanathan Anand. FIDE world champion 2000-2002, 2008; peak rating 2799

  • Grandmaster Anatoly Karpov. FIDE world champion 1993-1999; peak rating 2780

Observe that Topalov beats Anand, Anand beats Karpov, and Karpov beats Topalov (where “beats” means “wins more games than”).

The games thus resemble a noisy version of “rock paper scissors”.

The likelihood function does not record who played white; see karpov_kasparov_anand for such a dataset.

These objects can be generated by running script inst/rock_paper_scissors.Rmd, which includes some further discussion and technical documentation and creates file chess.rda which resides in the data/ directory.
