Statistics::RankOrder

Description

Statistics::RankOrder contains algorithms for determining overall rankings from a panel of judges. SYNOPSIS use Statistics::RankOrder; my $r = Statistics::RankOrder->new(); $r->add_judge( [qw( A B C )] ); $r->add_judge( [qw( A C B )] ); $r->add_judge( [qw( B A C )] ); my %ranks = $r->mean_rank; my %ranks = $r->trimmed_mean_rank(1); my %ranks = $r->median_rank; my %ranks = $r->best_majority_rank; This module offers algorithms for combining the rank-ordering of candidates by a panel of judges. For the purpose of this module, the term "candidates" means candidates in an election, brands in a taste-test, competitors in a sporting event, and so on. "Judges" means those rank-ordering the candidates, whether these are event judges, voters, etc. Unlike "voting" algorithms (e.g. majority-rule or single-transferable-vote), these algorithms require judges to rank-order all candidates. (Ties may be permissible for some algorithms). Algorithms included are: Lowest-Mean Trimmed-Lowest-Mean Median-Rank Best-of-Majority In this alpha version, there is minimal error checking. Future versions will have more robust error checking and may have additional ranking methods such as pair-ranking methods..
