8.2. For matched pairs, consider the special case (8.18) of the loglinear ordinal quasi-symmetry model (8.15), namely log ßij = ë + ki + Xj + ß\u, + ß2Uj + pi+j.

For equally spaced scores, explain why this model has the form

ßij = otiOijSi-j8*+j, which is in a class of models proposed by Goodman (1985).
