Comparison of a new expert elicitation model with the Classical Model, equal weights and single experts, using a cross-validation technique
The problem of ranking and weighting experts' performances when quantitative judgments are being elicited for decision support is considered. A new scoring model, the Expected Relative Frequency model, is presented, based on the closeness between central values provided by the expert and known values used for calibration. Using responses from experts in five different elicitation datasets, a crossvalidation technique is used to compare this new approach with the Cooke Classical Model, the Equal W
