摘要

Given a model of preferences, what choice data or experiment is sufficient to definitively test whether a subject is consistent with the model or to classify them into some type within the model? We characterize all experiments that test or classify a given model using a novel graph-theoretic construction: the labeled permutohedron. We show how these results can be used to identify the smallest experiments that achieve a particular goal.
