SAS Calculate AUC of Validation Data - listendata.com
Constructing ROC Curves with the SAS USING SAS TO CONSTRUCT AN ROC CURVE While the steps above are conceptually simple, the process of getting from the data set in Table 1 to the data set in Table 3 is less than straightforward with the SAS system, especially without the SAS/IML module. The approach discussed here allows the user to accomplish this task using only DATA steps, PROC SORT... between ROC curves for model results specified in the three ROC statements. To generate ROC contrasts, all terms used in the ROC statements must be placed on the model statement. The NOFIT option suppresses the fitting of the specified model. Because of the presence of the ROC and ROCCONTRAST statements, ROC plots are generated when ODS GRAPHICS are enabled. The …

  • ROC Curve . Introduction . Receiver operating characteristic (ROC) curves are used to assess the accuracy of a diagnostic test. The technique is used when you have a criterion variable which will be used to make a yes or no decision based on the value of this variable. The area under the ROC curve (AUC) is a popular summary index of an ROC curve. This module computes the sample size necessary
  • the data for the ROC curves so that you can create custom plots using SAS/GRAPH software. Most of the SAS code presented consists of SAS/STAT and SAS/GRAPH software; Base SAS is used occasionally to prepare the data for analysis and plotting.
  • Accurately Calculate AUC (Area Under the Curve) in SAS for a binary classifier rank ordered data. AUC is the area under a receiver operating characteristic (ROC) curve and is an important measurement on the accuracy of a binary classifier.
  • A ROC curve is created by connecting all ROC points of a classifier in the ROC space. Two adjacent ROC points can be connected by a straight line, and the curve starts at (0.0, 0.0) and ends at (1.0, 1.0).
