Abstract

For square contingency tables, Saigusa et al. [7] considered the partial symmetry model which indicates symmetry of cell probabilities for at least one of pairs of symmetric cells with respect to the main diagonal of the table. The present paper proposes (1) another partial symmetry model for symmetric pairs of cumulative probabilities for the square table, and (2) a measure to represent the degree of departure from the model. The measure has a form of weighted geometric mean of the diversity index including Shannon entropy in a special case. Examples are given.
