2.1 Introduction

One of the simplest scenarios for prediction is the case of a binary predictor. It is important not only because it contains the most critical building blocks of an ROC curve but also because it is often encountered in practice. This chapter uses an example from weather forecasting to illustrate the concepts. Problems dealing with similar data are abundant as well, ranging from diagnostic medicine to credit scoring.
