I've got a program that analyses some data based on a bunch of values then spits out a true/false value if it was correct or not. I'm using the Weka software to graph this all up and I just want to show the ROC curve for my data.
If I use the ZeroR classifier does it change the data in any way or does it just display the data?
I want to just show the results and get the ROC without changing/inferring any data - can I use ZeroR for this?
ZeroR classifier uses only the target (dependent variable) to build a majority classifier. As a consequence, it does not fit your purpose. You can built it from code as described here: Generating ROC curve example. Basically you do not need a classifier, you need only the results and an instance of ThresholdCurve class (this is how it is named in weka library).
