Hello,everyone. I'm newbie in Rapidminer.

I would like to ask one enquiry about the square_correlation in rapid miner

Why there is a range of +/- in square_correlation?
Is there any reason behind?

Hi,

you likely run a cross validation here. Each cross validation gives you different performances. The result you see is the average and the standard_deviation of the different results.

Best,

Martin
