摘要

In decision analysis and risk analysis, the best (sometimes the only) source of information regarding some variables of interest is often expert judgment. Since multiple experts can bring more information to the table than just a single expert, there is considerable interest in combining the judgments of multiple experts. This has led to an extensive interdisciplinary literature on the combination of forecasts, considering both point forecasts and probability forecasts. Contributors to the literature include scholars from statistics, decision theory/decision analysis, management science, psychology, economics, and areas of application as well as practitioners. The article by Bolger and Rowe considers the important question of whether the experts should be treated symmetrically in such aggregation.
