The receiver operating characteristic curve offersone way to measure effectiveness of prediction bycalculating the area under the curve (AUC) We present aSAS macro for calculating AUC that takes the surveyweights into account For comparing logistic regressionmodels one needs to assess differences in AUC against thevariation in the data
The Receiver Operating Characteristic (ROC) curve is a key tool for diagnostic test and has been used in identification of early clinical responses that could predict long-term outcomes [12] Youden's Index is often used in conjunction with ROC analysis[3] and the maximum value of Youden’s index may be used as a criterion for selecting the
