Figure 9-4. Meta data for the training data set (2nd_Heart_Attack attribute is present
with 'nominal' data type.) Note that all scoring ranges fall within all training ranges.
6) Switch back to design perspective and add a Set Role operator to your training stream.
Remember that if you designated 2nd_Heart_Attack to have a 'label' role during the
import process, you won't need to add a Set Role operator at this time. We did not do this
in the topic example, so we need the operator to designate 2 nd _Heart_Attack as our label,
our target attribute:
