Flipped ROC curve with roccomp command

[Bishoi Aziz]

Hello everyone,

I face a problem with roccomp command. I run it using three predictors. It graphs one curve to one side of the reference line, and the other two on the other side. I tried using only two predictors and the same problem happen. I want to have all the curves at one side. Here's how I write the command:
roccomp true v1 v2 v2, graph summary

I would appreciate if you can help with that.

Thanks

Bishoi
