Backtransforming the Predicted Values

  1. The prepared data includes a transformation of sales, so the predicted values from this model are not directly usable as scores. To transform the predicted values into the original scale, from the menus choose:

    Transform > Prepare Data for Modeling > Backtransform Scores...

    Figure 1. Backtransform Scores dialog
    Backtransform Scores dialog
  2. Select Predicted Value for sales_transformed [PRE_2] as the field to backtransform.
  3. Type _backtransformed as the suffix for the new field.
  4. Type workingDirectory\car_sales_transformations.xml, substituting the path to the file for workingDirectory, as the location of the XML file containing the transformations.
  5. Click OK.
