When you train your model, the training is actually done on the first half of the database, which means the second half contains data that have not been used for training.
The window you obtain when you press "Test" in the Model Manager is:
You can test any of the submodels you want by selecting it and pressing "Test Selected Model":
When you test a model, the Model Manager calculates predictions using the whole database, and compare them with the actual target values. It divides the results into training set (for which the agreement is expected to be good since these are data that have been used to build the model) and testing set (for which the agreement is always worse, because these are unseen data).
The calculation time for the
predictions can be relatively long
(a few minutes), but the results are all saved. This means that, once you have
tested, say, the first model, the time you have to wait if you later repeat
this will be much shorter.
This will also shorten the time required in the first step of the committe
preparation.
