"ROC confidence limits"

Hi,
perhaps you don't have confidence attributes in your data?

Greetings,

Sebastian,

Thank you for your help!  I checked for that; they are there (in the performance export file).


<com.rapidminer.tools.math.ROCPoint id="246">
                <falsePositives>139.0</falsePositives>
                <truePositives>68.0</truePositives>
                <confidence>0.19407850064775464</confidence>
</com.rapidminer.tools.math.ROCPoint>
 

But, I can't figure out how to turn on the confidence band in the ROC plot.  I'd also like to know exactly what it represents; how, for instance, does it relate to the confidence value in the performance export file, is it the height of the shaded region?  I'd also like to know where this confidence comes from / how computed?


If you have any answers or can point me in the right direction I'd appreciate it!

Thanks!
brian

I think the question has been answered here:

Thank you Steffen,
this saved me a lot of either work or inconvenience by pointing Brian on the source code

Thanks to you both Sebastian and Steffen!
