Multiplicative models with further restrictions on the usual symmetry model
Sadao Tomizawa · Communication in Statistics- Theory and Methods · 1992
For square contingency tables with ordered categories, this paper proposes some multiplicative models with further restrictions on the usual symmetry model but they are not so strict as in the double symmetry model considered by Tomizawa (1985a). Each of the proposed models has the structure of symmetry about the main diagonal plus an asymmetry about the reverse diagonal of the square table. Each of the models is unsaturated on the main diagonal. The models are applied to two data sets of unaided distance vision.
