You have built a stream in SPSS MODELER that includes two source nodes and four output nodes. How can you run the stream to produce all four outputs?

To produce all four outputs in your SPSS Modeler stream, clicking the Run button from the main menu initiates the entire process from all source nodes through to all output nodes. This action ensures that the entire stream, including the pathways leading to each of the output nodes, is executed, allowing you to generate results for all defined outputs.

By utilizing the main menu Run button, you are effectively instructing the software to handle all dependencies and processes within the stream simultaneously. This is particularly important when your model involves more than one source node, as each source might contribute to different or overlapping aspects of the output. Consequently, this choice ensures that every part of the model is executed in sequence as needed.

In contrast, choosing other options would limit the execution to a specific node or selection, which would not fully harness the capabilities of the entire stream to generate all desired outputs. For example, running a selection from a source node or executing only one terminal node may yield incomplete results and overlook the contributions from other parts of the stream. Thus, selecting the main menu's Run button is the most comprehensive approach to achieving the objective of producing all outputs.
