Abstract
A method is proposed, which analyzes and represents anti-symmetric part of asymmetric relational data, dealing simultaneously with symmetric part as distance by the classical MDS. The similarity to the author's previous formulation is mentioned and the difference is clarified. Furthermore, it is shown that the data can be represented by complex vectors when relational data is given as complex numbers and that the data can be transformed to inner product-like relational data as analyzed in former researches when it is given as distance-like relational data.
