TITLE:  Bayesian Analysis of Rank Data with Application to Primate Intelligence Experiments

ABSTRACT:

A model for analyzing rank data obtained from multiple evaluators, possibly
using different ranking criteria, is proposed. The model is specified
hierarchically within the Bayesian paradigm and includes parameters that
represent the probabilities that two items are assigned equal
rankings.  Also included are parameters that account for the relative
precision of rankings obtained from distinct evaluation schemes.  The model
is illustrated through a meta-analysis of rank data collected for the
purpose of comparing  the cognitive abilities of various primate genera.
