a probabilistic lexicographic model A lexicographic rule orders alternatives over attributes by first evaluating on the most important attribute and then, if there are ties, on the second most important attribute, and so forth. Previous research has specified mathematical representations and inference procedures of lexicographic rules. However, these methods assume that subjects make deterministic decisions when using a lexicographic rule. We extend the previous literature by exploring the possibility of probabilistic decisions by subjects using a lexicographic rule. |
