I personally use the -senspec- package, which computes sensitivity, specificity and/or false positive rate in variables, which you can then graph using -twoway line-.

I hope this helps.

Best wishes

I am calculating ROC AUC statistics to compare logistic regression

I was wondering if anybody knows a way of drawing a ROC curve graph to
viusally compare several curves after I have run the somersd command.
