d_dublinwest: Dublin West Data (partial orderings)

In PLMIX: Bayesian Analysis of Finite Mixtures of Plackett-Luce Models for Partial Rankings/Orderings

Description

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.

Usage

data(d_dublinwest)

Format

Object of S3 class c("top_ordering","matrix") gathering a partial orderings with N=29988 rows and K=9 columns. Each row lists the candidates from the most-liked (Rank_1) to the least-liked (Rank_9) in a given voting ballot.
