Robust Rankings of Multidimensional Performances: An Application to Tour de
France Racing Cyclists
Dr. Knut M. Wittkowski (The Rockefeller University) pointed out that his u-score given in Equation 3 of Wittkowski (2003) and Equation 3 in Wittkowski, Lee, Nussbaum, Chamian, and Krueger (2004) is the same as our net-dominance-metric that aggregates the information provided by our dominance-metric
in Equation 2 of Cherchye and Vermeulen (2006). This note is to acknowledge the priority of the work by Wittkowski and his coauthors of which the present authors had unfortunately not been aware.
