Using the final models identified in problems 1 and 2 compare the estimates of the coefficients obtained from fitting the multinomial logistic regression model to those obtained from fitting the adja- cent-category, continuation-ratio and proportional odds ordinal lo- gistic regression models. For the mammography experience data recode the outcome variable, ME, to 0 = Never, 1 = Over one year ago and 2 = Within one year in order that its codes increase with frequency of use.
