Apr 9, 2017 at 1:45 comment added Doug Fir @TheLaconic thanks for contributing to the discussion. You don't see the relevance of cross-validation here. OK. But I was not sure. That's why I asked a question on this q&a site... out of lack of understanding!
Apr 9, 2017 at 1:41 comment added The Laconic I don't see the relevance of cross-validation here in particular. The idea is that you have to compare apples to apples, whatever your metric. This is conceptually distinct from the process of comparing the performance of two models on test data. Edit: I take that back. I can see that performance on test data is important here, since one model could be directly optimizing the performance measure in-sample, while the other wouldn't. But it does still have to be apples-to-apples.
