Workspace Node: Random Forest Regression - Specifications - Quick Tab
The Random Forest Regression workspace node can be accessed from the Feature Finder, the ribbon bar, or the Node Browser. The Specifications - Quick tab is displayed by default when the specifications dialog box is opened.
| Element Name | Description |
|---|---|
| Variables | Click this button to display a four-variable list selection dialog box from which you can select the dependent variable, categorical and continuous predictors, and the count variable (optional).
From the first list, select the dependent variable. From the second list, select the categorical predictors. Note that these variables must contain text or numeric codes that identify the classes or groups to which each case or observation belongs. From the third list, select the continuous predictors. From the fourth list, select the count variable. This variable is optional. If selected, it will be used as a case-multiplier in the analysis. Thus, you can analyze input data that have previously been aggregated (tabulated). |
| Factor codes | Once you have selected a categorical predictor variable, the option for the selection of the factor codes will be available. Click the
Factor codes button to display the Select Codes for Independent Variables dialog box, where you can select codes for the categorical factors or predictors. The list of codes can be displayed by clicking the
Zoom button. Note that you must select at least two codes for each of the selected categorical factors.
Options / C. See Common Options. |
| OK | Click the OK button to accept all the specifications made in the dialog box and to close it. The analysis results will be placed in the Reporting Documents node after running (updating) the project. |
