7. Consider the two-class logistic model with the linear predictor: p(x) log( ·1 - p(x)) = Bo + B₁x₁ + ß₂x2 + … + ßpïp. (a). Write down an expression for the odds (b). Show that the odds ratio O(x) = = p(1|x) p(2|x)* comparing the odds for two new cases with explanatory variables x and x' does not depend on Bo. (c). What does this imply if we simply want to rank new cases in terms of p(1|x).
