> In some of the regression algorithms, we return several metrics. One of these is R2. But we call if PLAIN_R2. This is unconventional. We should just call it R2. I've never see the term PLAIN_R2 in any book or paper or software etc. There is R2 and Adjusted R2. I think it would be better to use the conventional terminology as mush as possible.
