Comment on Cookeʹs classical method

Several of the papers in this special issue are in one way or another linked to Cookeʹs “classical” method for combining expert probability distributions. This comment focuses on characteristics of that method. In particular, I consider two questions: does the weighting scheme give the experts a positive incentive to report their beliefs honestly for each variable? How does Cookeʹs method perform when evaluated out-of-sample?
