Abstract: For square contingency tables, models having a structure of double symmetry have been proposed. The double symmetry indicates that both structure of symmetry and point symmetry hold. For measuring the degree of departure from model having structure of double symmetry, we propose a two-dimensional measure vector that can simultaneously measure the degree of departure from symmetry and the degree of departure from point symmetry. Using the proposed measure vector, we can see the degree of departure from double symmetry, while distinguishing the degree of departure from symmetry and the degree of departure from point symmetry.
