Preparing the Data
- To run automated data preparation in automatic mode, from the
menus choose:
Figure 1. Objective tab 
- Select Optimize for accuracy.
Since the target field, Sales in thousands, is continuous and could be transformed during automated data preparation, you want to save the transformations to an XML file in order to be able to use the Backtransform Scores dialog to convert predicted values of the transformed target back to the original scale.
- Click the Settings tab, then click the Apply
and Save settings.
Figure 2. Apply and Save settings 
- Select Save transformations as XML and click Browse to navigate to workingDirectory/car_sales_transformations.xml, substituting the path you want to save the file to for workingDirectory.
- Click Run.
