Abstract
This paper proposes a general method capable to process paired comparison data with order effect. The method is able to estimate psychological interval scale and to estimate the degree of order effect.
First, conditions that the model should satisfy are investigated. And it is indicated that band-function model satisfies such conditions. Next, some properties about order effect are defined on band function model. Third, the algorithm to obtain interval scale is reviewed. Then, in order to estimate characteristics of judgement from paired comparison data and psychological interval scale, an algorithm for curve fitting is proposed. Last the whole method proposed in this paper is applied to the paired comparison data about discomfort of burst sound. Results assures that order effect and psychological interval scale is estimated by this method. Furthermore, the psychological interval scale is compared with LA, slow-max value as physical scale on burst sound.
