The Use of Multivariate Analysis for the Final Evaluation of the Results of Expert Assessments

Abstract

We developed an alternative to summation score method for assessing the results of expert evaluations. The method is based on representation of the objects to be examined in the form of points of multidimensional space in a coordinate system with axes corresponding to experts estimations, the dimension of the space being equal to the number of experts. A distance to the object with the best possible estimations (according to the rule: the smaller the distance, the preferable object) is used as a criterion for final evaluation of the objects with a possibility of their further ranking according to the degree of preferences. For example, expert estimations of tasting wine demonstrated that the developed method is more representative and mathematically justified compared to traditional aggregation of points.
