It sounds like you are implying one should act as though one doesn't know one's test data's y-values, as one wouldn't with actual new data. You then sugget that one should use MSE instead of R^2: However, I shall like to remark that I don't see how using MSE instead of R^2 frees me from intercept differences (MSE is not relying on the mean, but still intercept-sensitive). I was then thinking about using the correlation between predicted and observed values, what do you think about that? | |
