Abstract

ERG data measured by Riggs et al. was analysed by use of some multivariate techniques. The results were compared with those derived by their trial and error method based on the psychophysical point of view, especially in the estimation of chromaticity diagram. The multivariate techniques applied are Torgerson-Gower method(i. e. principal coordinate analysis), Shepard-Kruskal method(well known nonmetric multidimensional scaling), and a new method proposed by one of the authors, T. I. The features of the three methods were discussed during the course of analysing the ERG data. The chromaticity diagram predicted in the present study satisfied the psychophysical requirements better than that predicted by Riggs et al. In addition, the present analysis allowed to estimate the noise component in the observed ERG data and clarified their latent structures.
