Unanimity and Compromise Among Probability Forecasters
研究当两位预测者对不确定事件的概率判断一致时,决策者是否应采纳该概率,并检验多种贝叶斯共识模型是否符合一致与妥协原则,利用气象概率预测数据评估模型表现。
When two forecasters agree regarding the probability of an uncertain event, should a decision maker adopt that probability as his or her own? A decision maker who does so is said to act in accord with the unanimity principle. We examine a variety of Bayesian consensus models with respect to their conformance (or lack thereof) to the unanimity principle and a more general compromise principle. In an analysis of a large set of probability forecast data from meteorology, we show how well the various models, when fit to the data, reflect the empirical pattern of conformance to these principles.
