8.1 Introduction

Our discussions so far have focused on a single predictor. Other variables were considered, such as when comparing several predictors or covariate-adjusted ROC curves, but not in the form of producing predictions from multivariable models and evaluating their accuracy. Chapters 8 and 9 deal with this problem.
