Boosted Trees Startup Panel and Quick Tab

Ribbon bar. Select the Data Mining tab. In the Trees/Partitioning group, click the Boosted Trees Classifiers and Regression icon to display the Boosted Trees Startup Panel.

Classic menus. On the Data Mining menu, select Boosted Trees Classifiers and Regression to display the Boosted Trees Startup Panel.

The Startup Panel contains one tab: Quick. Use the options on this tab to choose the Type of analysis to be performed, i.e., whether the analysis involves the prediction of a categorical or class variable (Classification Analysis) or continuous variable (Regression Analysis).

See also the Boosted Trees Index, Overviews, and Examples.

Type of analysis

This group box contains two options: Classification Analysis and Regression Analysis.

Classification Analysis

Select Classification Analysis if the dependent or outcome variable is a categorical or class variable, and the purpose of the analysis is to compute predicted classifications.

Regression Analysis

select Regression Analysis if the dependent or outcome variable is a continuous variable, and the purpose of the analysis is to compute predicted values.

OK

Click the OK button to display the Boosted Trees Specifications dialog box, where you can select the variables and specify other options for this analysis.

Cancel

Click the Cancel button to close the Startup Panel without performing an analysis.

Options

See Options Menu for descriptions of the commands on this menu.

Open Data

Click the Open Data button to display the Select Data Source dialog box, which is used to choose the spreadsheet on which to perform the analysis. The Select Data Source dialog box contains a list of the spreadsheets that are currently active.

Select Cases

Click the Select Cases button to display the Analysis/Graph Case Selection Conditions dialog box, which is used to create conditions for which cases will be included (or excluded) in the current analysis. More information is available in the case selection conditions overview, syntax summary, and dialog box description. Note that other options are provided in the subsequent dialogs to specifically identify observations that are to be used as a test sample (see also the Overview for details).

W

Click the W (Weight) button to display the Analysis/Graph Case Weights dialog box, which is used to adjust the contribution of individual cases to the outcome of the current analysis by "weighting" those cases in proportion to the values of a selected variable. In the STATISTICA Boosted Trees module, weights are interpreted as simple case multipliers.
