Hello, is there a class in weka to draw a ROC curve?
This is from http://www.cs.waikato.ac.nz/~ml/weka/tips_and_tricks.html
"Access to visualization from the ClassifierPanel [...] panel is
available from a popup menu. Click the right mouse button over an entry
in the Result list to bring up the menu. You will be presented with
options for viewing or saving the text output and---depending on the
scheme---further options for visualizing errors, [...] trees etc."
One of the options, called "Visualize threshold curve" allows you
visualize ROC curves, etc.
