# Monte Carlo cross validation (MCC)

After running MCC, will the result displayed be for the whole data or the testing data. I read MCC uses 2/3rd data for training and 1/3rd for testing but while checking my results i still see results for whole data and not only for the testing data. I need clarity on how i can get only testing result data. Thank you.

The data are split not once, but many times -- in normal (k-fold) cross validation there are $k$ such splits and each observation will be both in the test set (for one split) and in the training set (in the remaining ones).
