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

    $\begingroup$ 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? $\endgroup$ – Nick Sabbe Aug 8 '11 at 13:59

    $\begingroup$ See my answer to your previous question -- I think it is a pretty straightforward description of ROC. $\endgroup$ – user88 Aug 8 '11 at 14:28

    $\begingroup$ 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. $\endgroup$ – Frank Harrell Aug 9 '11 at 13:21
  • $\begingroup$ @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 $\endgroup$ – Simplicity Aug 10 '11 at 15:54
  • $\begingroup$ Programmers’ Niche in this document, p.33, would be a great read. $\endgroup$ – nalzok Mar 15 at 2:07

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.
