group. Note that there are fewer registrations than subjects (140 *vs.* 150) in this setup, as our priority is to maintain the overall diagnostic ratio.

0.5ex For both, `ADNI-1` and `ADNI-2`, the remaining 5/6 of the data is used for testing. We trained four prediction models and their four corresponding correction models, leading to eight prediction models in total, listed in Table \[table:predictionmodels\]. We also note that the training sets within `ADNI-1` and `ADNI-2`, resp., were not overlapping.
