I want to build a classification model in Predictive Analytics. As described in the documentation "Test (optional): used to compute the final model quality indicator." Can you explain for which specific indicators the test dataset is used? As I understand, test dataset does not influence the Ki and KR. I'm right?

For some reason I could not access the documentation page you mention.

As per the documentation below, the Test subset allows the user to Verify the performance of the selected model on a new dataset.

https://help.sap.com/viewer/ab7d3e90e8364cd986c3ca6ecef51e99/3.2/en-US/5ddb40935dab438489f560dbfb5993a7.html

Note that the selection of the best model is always based on the validation subset whether you are using a Test dataset or not.

Here are examples of model performance graphs or reports where one can see the Test subset:

Display > Model Graphs > Datasets > All Datasets

Display > Statistical Reports > Model Performance > Estimator Variables / KI & KR / Other Performance Indicators.

I understand that the test dataset is not involved in choosing the best model. Only in statistical reports. Thank you.
