What is the way to get the value ok Kappa in

I'm trying to get this value to add to an example set ("Create exampleset") but there is no result with the advanced function "param("My Kappa name operatror", ...)". Is this the way?

Do I have to use something like "Kappa.performace"?

Hi @vgpowered ,

For me it is not 100 % clear what you want to achieve. Could you maybe post your process xml (and best a sample data set) (How-To share process xml: https://community.rapidminer.com/discussion/51369) and explain a bit more in detail which value do you want to extract and add to an ExampleSet.

Best regards,
Fabian

Thank you very much. I only need the value of kappa in an exampleset and now I have discovered you need the special operator "Performace to Data" to get it.

It would be interesting to have a generic operator to do that. This was the reason I was triying with "Create Exampleset" with no success.
