The Dublin West dataset (d_dublinwest
) contains the results of the
voting ballots of the 2002 Irish general election from the Dublin West
constituency. The Irish voting system allows voters to rank the candidates
in order of preferences, rather than only specify the favorite one. In the
Dublin West constituency, N=29988 voters ranked a maximum of K=9
candidates, labeled as: 1 = Bonnie R., 2 = Burton J., 3 = Doherty-Ryan D., 4
= Higgins J., 5 = Lenihan B., 6 = McDonald M., 7 = Morrissey T., 8 = Smyth
J. and 9 = Terry S.. The dataset is composed of partial top orderings of
varying lengths. Missing positions are denoted with zero entries.
