SAS 9.1

SAS 9.1 provides basic ROC commands within the main package through the Proc Logistic command. Documentation and examples from the reference manuals are here. Briefly, the following tasks can be done:

• plot one empirical ROC curve from a logistic regression model
• estimate nonparametric AUCs through a c-statistic

When fitting a Proc Logistic, specify a dataset for outroc= in the model line. Then use Proc Gplot to plot the ROC curve.
