Analyzing Receiver Operating Characteristic Curves with SAS

Preface

When I received my Ph.D. in statistics, I had not heard the term receiver operating characteristic (ROC) curve. Like most biostatisticians, my introduction to ROC curves came through my involvement in studies of medical diagnostics. Later, I realized that they are used, although not as much as they should be, in other fields, such as credit scoring and weather forecasting, which make intensive use of statistical prediction methods. As my exposure grew, I needed more options in SAS to analyze ROC curves. However, over time, I realized that SAS offers more on ROC curves than I initially thought. I also accumulated a good deal of statistical knowledge and SAS tricks on ROC curves that may be helpful for those who now find themselves where ...
