The flow editor in Watson Studio presents a very cool graphical view of a model while you build it by combining various types of nodes representing objects or actions. The flow editor has three palettes that you can choose from: SPSS modeler nodes, Spark ML algorithm nodes, and neural network nodes. In this example, we’ll create an SPSS modeler flow.

Note: SPSS is the abbreviation of Statistical Package for Social Sciences and it is used by researchers to perform statistical analysis. The technology was acquired by IBM in 2009. The current versions (2015) are named IBM SPSS Statistics.
