GCHAID Results - Node Tab
Select the Node tab of the GCHAID Results dialog box to access the options described here.
| Element Name | Description |
|---|---|
| Node id | Select terminal or split node in this box; all other results computed from options on this tab will pertain to this node. |
| Data belonging to node | Click this button to create a spreadsheet containing the data belonging to the node selected in the option Node id. Simultaneously, a parallel coordinate plot for these data will be produced for the selected node, showing the pattern of values for the observations belonging to this node, across the predictor variables. This graph is extremely useful for identifying "typical patterns" of predictor values for particular terminal classifications or nodes. |
| Histogram of DV belonging to node | Click this button to produce a histogram of responses for the data belonging to the selected node. |
| Splitting criterion | Click this button to create a spreadsheet containing the splitting information about the selected node, such as the splitting variable and the splitting categories. |
| SQL code (selection rules) | Click this button to generate the rules for classifying observations into the respective node (as selected in the Node id field), in the form of SQL code. To generate SQL code for all terminal nodes, use the SQL code for all terminal nodes option on the GCHAID Results dialog box - Report tab. |
