7. Consider the twoclass logistic model with the linear predictor: MK) 1p(x)) :50+)81331+2$2+...+,8p$p, log( (a). Write down an expression for the odds (b). Show that the odds ratio 3(3)) comparing the odds for two new cases with explanatory variables x and x, does not depend on 60. (c). What does this imply if we simply want to rank new cases in terms of p(1|x)
