7.26 For the linear-by-linear association model applied with column scores

{vj = j }, show that the adjacent-category logits within row i have form (6.6), identifying αj with (λY j+1

− λY j ) and the row scores {ui } with the levels of x.

In fact, the two models are equivalent. The logit representation (6.6) provides an interpretion for model (7.11).
