Are there tutorials you recommend that teach how to draw an ROC curve?

Thanks.

I think you need to be more precise. Do you want to draw them by hand (don't), or use a specific piece of software (R, SPSS, ...)? What exactly is your problem with drawing them? – Nick Sabbe Aug 8 '11 at 13:59

See my answer to your previous question -- I think it is a pretty straightforward description of ROC. – mbq♦ Aug 8 '11 at 14:28

The most important thing to learn is WHEN to draw ROC curves. 95% of the examples that I have seen are unnecessary and do not represent the best approach to the problem. – Frank Harrell Aug 9 '11 at 13:21
@Nick Sabbe. Since I'm trying to learn how to plot an ROCcurve, a tutorial to show you the steps and how it is built would be fine, but I will surely use a software for that. Thanks – Med-SWEng Aug 10 '11 at 15:54

If you want to learn how to draw ROC curves by hand, wikipedia is a good place to start.
If you just want to calculate a plot a ROC curve, and don't really care to learn how the math works, try the colAUC funcion in the caTools package in R.

I believe most major stats packages can drawn ROC curves as well, and a little googling should help you find the appropriate commands.
