Refer to the logit model in Problem 5.23. Let A denote the response variable, opinion on abortion.

a. Give the symbol for the loglinear model that is equivalent to this logit model. Which logit model corresponds to loglinear model (AR, AP, GRP)?

b. State the equivalent loglinear and logit models for which: (i) A is jointly independent of G, R, and P, (ii) There are main effects of R on A, but A is conditionally independent of G and P, given R, (iii) There is interaction between P and R in their effects on A, and G has main effects.
