Rice Voting Data (partial orderings)

Description

The Rice Voting dataset (d_rice) collects the results of the 1992 election of a faculty member to serve on the Presidential Search Committee in the Rice University. A total of N=300 people casted their vote in the ballots by ranking the K=5 candidates in the short list in a preferential manner. The dataset is composed of partial top orderings of varying lengths. Missing positions are denoted with zero entries.

Format

Object of S3 class c("top_ordering","matrix") gathering a matrix of partial orderings with N=300 rows and K=5 columns. Each row lists the faculty members from the most-liked (Rank_1) to the least-liked (Rank_5) in a given voting ballot.
