Refer to the independence model, ij = i j . For the corresponding loglinear model (8.1): a. Show that one can constrain

Refer to the independence model, µ_ij = µα_i β_j. For the corresponding loglinear model (8.1):

a. Show that one can constrain ∑λ_i^X = ∑λ_j^Y = 0 by setting

b. Show that one can constrain λ₁^X = λ₁^Y = 0 by defining λ_i^X = log α_i – log α₁ and λ_j^Y = log β_j – log β₁. Then, what does λ equal?
