In a few posts I have mentioned Reciever Operator Curves (ROC), and a few folks have asked what I mean, so I want to explain it. This is an extremely important concept in medicine, and in decision making in general. Unfortunately, it is also quite complex. So complex in fact, that it is possible to explain an ROC in very high end mathematical speaking, such that few would understand (and yes, it can get over my head as well.) To see this kind of explanation, check out the Wikipedia entry on the ROC. But I want to try to make it a little simpler.
