Spss modeler 18 tutorial
This bypasses the context menu we saw previously, and goes directly into the node itself so we can edit it. Most often you will probably either edit the node or connect nodes. You can edit, add comments, copy, delete a node, connect nodes, and so on. Notice that there are many things you can do within this context menu. Once a node has been brought onto the stream canvas, typically at this point you will want to edit the node so that you can specify which fields, cases, or files you want the node to apply to. The Database node represents the action of reading data into Modeler from an ODBC compliant database.

If you wish to move the node within the stream canvas, select it by clicking on the node, and while holding the left mouse button down, drag the node to a new position. This node represents the action of reading data into Modeler from a delimited text data file. Move the cursor over the stream canvas.Ī copy of the selected node now appears on the stream canvas.This will cause the icon to be highlighted. Method one: Click on palette and then on stream: There are three ways to add nodes to a stream from a palette: To begin a new stream, a node from the Sources palette needs to be placed on the stream canvas. The middle button (optional) is used for connecting and disconnecting nodes.The right button is used for invoking context (pop-up) menus that allow for editing, connecting, renaming, deleting, and running nodes.The left button is used for selecting, placing, and positioning nodes on the stream Canvas.When building streams within Modeler, mouse buttons are used in the following ways: When building streams, mouse buttons are used extensively so that nodes can be brought onto the canvas, connected, edited, and so on. Given that you will spend a lot of time building streams, in this section you will learn the most efficient ways of manipulating nodes to create a stream. The following diagram is an example of nodes on the canvas, as well as a stream:

A stream represents the flow of data going through a number of operations (nodes). So once nodes have been placed on the stream canvas, they need to be linked together to form a stream. Remember that nodes represent operations to be carried out on the data.

This means that you will not be writing code for your data mining projects instead you will be placing nodes on the stream canvas. SPSS Modeler allows users to mine data visually on the stream canvas.

This book gives you a quick overview of the fundamental concepts of data mining and how to put them to practical use with the help of SPSS Modeler. The following excerpt is taken from the book IBM SPSS Modeler Essentials, co-authored by Keith McCormick and Jesus Salcedo.
