How to define which fields must be included in a new Dataset in Portrait Miner


 
The question is: do all fields and variables have to be included in a new dataset copied from an existing one, if only some of them are being used in the model?

The answer is: no, you only have to include the fields that are used, or possibly fields you think might be used in the future.
