In SPSS Modeler, what node allows you to preview thumbnails of data with different formulas applied?

In SPSS Modeler, the node that allows you to preview thumbnails of data with different formulas applied is the Transformation node. This node is designed to facilitate data manipulation and transformation by allowing users to apply various mathematical and statistical formulas to the data set.

When utilizing the Transformation node, users can see how different formulas affect their data in real-time, enabling them to visualize potential changes before committing to these transformations. This feature is particularly useful for exploring the implications of various transformations on the data set and selecting the most appropriate ones for further analysis.

In contrast, other options like Filler, Binning, and Filter serve different purposes. The Filler node is primarily used to fill in missing values within the data, while the Binning node categorizes continuous variables into discrete categories. The Filter node is focused on selecting a subset of data based on specified criteria. These functionalities do not include the ability to preview the effects of formulas applied to the data, which is why the Transformation node is the correct choice.
