Hello.
I would like to know, if I can use in RapidMiner my own formula for evaluating results. In hydrology exist so called Nash–Sutcliffe model efficiency coefficient (http://en.wikipedia.org/wiki/Nash–Sutcliffe_model_efficiency_coefficient)  . I do not fully understand user-based Performance - is it meant for this? Or maybe some combination of predicted and real labels can be evaluated? (by Generating attributes?)
Thanks,
Milan

    Hello

    I would use "generate attributes" to do the calculation. There would be a need to use macros. To get the result into a performance vector you could log the calculated result, turn this into another single row example set using "log to data" and then use "extract performance" to read this value.
