Dr. Patrick Barrie, PhD, MRSC, CEng, MIChemE, Cchem, MA, BA, of the Department of Chemical Engineering and Biotechnology at Cambridge University, UK, presents A new sports ratings system: The tiddlywinks world ratings in the Journal of Applied Statistics Volume 30, Issue 4, 2003
“After each tournament, a ‘tournament rating’ is calculated for each player based on how many points the player achieved and the relative strength of partner(s) and opponent(s). Statistical analysis is then used to estimate the likely error in the calculated tournament rating. Both the tournament rating and its estimated error are used in the calculation of new ratings. The method has been applied to calculate tiddlywinks world ratings based on over 13 r 000 national tournament games in Britain and the USA going back to 1985.”
