d_rice: 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.

Usage

data(d_rice)

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.
