multiple ROC curves in one image

Hello,

I need to have multiple ROC curves from several Bayesian models (predicting the same class) in one image.

Something like this: http://www.medsci.org/v04/p0249/ijmsv04p0249g02.jpg

Is it possible to do this with some KNIME's node?


Thanks for reply :)

 

Sure. The ROC node can plot as many curves as you like. Just select them in the node configuration dialog.

Well I am not sure what do you mean. There are only "Columns containing the positive class probabilities".

The node's description explains in detail, how the node works.

I have got it, thanks :)

You just need to join test data passed through different Bayesian predictors and add its class probability in ROC node configuration.
