comment Is it a good idea to evaluate cross-validation using correlation coefficient?
Ok, I see now! But in my particular case, different intercept and slope is not a problem (it would be hard to explain why). So is there any other problem of the correlation coefficient besides the illustrated one with intercept and slope? If not, I consider it perfect measure for my case!!

comment Is it a good idea to evaluate cross-validation using correlation coefficient?
Hi Hong Ooi, I didn't understand your example. The correlation of the two vectors is -1, so the predictions are terrible. I would consider model as good when r is between 0.5 and 1.
