"[Solved] Performance measurement with trend direction"
I am looking for a certain kind of performance measurement. "Relative error" for example gives an idea to which degree the prediction fits the label. But in my special case I also want to know whether the prediction over- or underestimates the label.
A workaround might be to use something like "average(prediction) - average(label)" in addition to the relative error. But of course it would be better to have this in one operator.
Please let me know your ideas...
