IBM SPSS Modeler Overview
FieldOps. Nodes perform operations on data fields, such as filtering, deriving new fields, and
determining the measurement level for given fields.
Graphs. Nodes graphically display data before and after modeling. Graphs include plots,
histograms, web nodes, and evaluation charts.
Modeling. Nodes use the modeling algorithms available in SPSS Modeler, such as neural nets,
decision trees, clustering algorithms, and data sequencing.
DatabaseMo deling. Nodes use the modeling algorith ms available in Microsoft SQL Server,
IBM DB2, and Oracle databases.
Output. Nodes produce a variety of output for data, charts, and model results that can be
viewed in SPSS Modeler.
Export. Nodes produce a variety of output that can be viewed in external applications, such
as IBM® SPSS® Data Collection or Excel.
SPSSStatistics. Nodes import data from, or export data to, IBM® SPSS® Statistics, as well as
running SPSS Statistics procedures.
As you become more familiar with SPSS Modeler, you can customize the palette con tents for
your own use. For more information, seethe topic Custo mizing the Nodes Palette in Chapter 12
on p. 223.
Located below the Nodes Palette, a report pane provides feedback on the progress of various
operations, such as when data is being read into the data stream. Also locat ed below the Nodes
Palette, a status pane provides information on what the application is curren tly doing, as well as
indications of when user feedback is required.
IBM SPSS Modeler Managers
At the top right of the window is the managers pane. This has three tabs, which are used to
manage streams, output and models.
Youcan use the Streams tab to open, rename, sa ve,a nd delete the streams created in a session.

Streams tab
The Outputs tab contains a variety of files, such as graphs and tables, produced by stream
operations in IBM® SPSS® Modeler. You can display, save, rename, and close the tables, graphs,
and reports listed on this tab.
