Bootstrap Forest Platform Options

The Bootstrap Forest red triangle menu contains the following options:

Plot Actual by Predicted

(Available only for continuous responses.) Provides a plot of actual versus predicted values.

Column Contributions

Displays a report that shows each input column’s contribution to the fit. The report also shows:

– The total number of splits defined by a column.

– The total G2 (for a categorical response) or SS, sum of squares (for a continuous response), attributed to the column.

– A bar chart of G2 or SS.

– The proportion of G2 or SS attributed to the column.

Show Trees

Provides various options for displaying trees in the Tree Views report. The report gives a picture of the tree that is fit at each layer of the boosting process. For a description of the Prob column shown by the Show names categories estimates option, see Predicted Probabilities in Decision Tree and Bootstrap Forest in the Partition Models section.

ROC Curve

(Available only for categorical responses.) See ROC Curve in the Partition Models section.

Lift Curve

(Available only for categorical responses.) See Lift Curve in the Partition Models section.

Save Columns

Contains options for saving model and tree results, and creating SAS code.

Save Predicteds

Saves the predicted values from the model to the data table.

Save Prediction Formula

Saves the prediction formula to a column in the data table. The formula consists of nested conditional clauses that describe the tree structure. If the response is continuous, the column contains a Predicting property. If the response is categorical, the column contains a Response Probability property.

Save Tolerant Prediction Formula

(The Save Prediction Formula option should be used instead of this option. Use this option only when Save Prediction Formula is not available.) Saves a formula that predicts even when there are missing values and when Informative Missing has not been selected. The prediction formula tolerates missing values by randomly allocating response values for missing predictors to a split. If the response is continuous, the column contains a Predicting property. If the response is categorical, the column contains a Response Probability property. If you have selected Informative Missing, you can save the Tolerant Prediction Formula by holding the Shift key as you click the report’s red triangle.

Save Residuals

(Available only for continuous responses.) Saves the residuals to the data table.

Save Cumulative Details

(Available only if validation is used.) Creates a data table containing the fit statistics for each tree.

Publish Prediction Formula

Creates a prediction formula and saves it as a formula column script in the Formula Depot platform. If a Formula Depot report is not open, this option creates a Formula Depot report. See Formula Depot.

Publish Tolerant Prediction Formula

(The Publish Prediction Formula option should be used instead of this option. Use this option only when Publish Prediction Formula is not available.) Creates a tolerant prediction formula and saves it as a formula column script in the Formula Depot platform. If a Formula Depot report is not open, this option creates a Formula Depot report. See Formula Depot. If you have selected Informative Missing, you can use this option by holding the Shift key as you click the report’s red triangle.

Make SAS DATA Step

Creates SAS code for scoring a new data set.

Specify Profit Matrix

(Available only for categorical responses.) Enables you to specify profit or costs associated with correct or incorrect classification decisions. See Show Fit Details in the Partition Models section.

Profiler

Shows a Prediction Profiler. See Profiler in Profilers.

See Local Data Filter, Redo Menus, and Save Script Menus in Using JMP for more information about the following options:

Local Data Filter

Shows or hides the local data filter that enables you to filter the data used in a specific report.

Redo

Contains options that enable you to repeat or relaunch the analysis. In platforms that support the feature, the Automatic Recalc option immediately reflects the changes that you make to the data table in the corresponding report window.

Save Script

Contains options that enable you to save a script that reproduces the report to several destinations.

Save By-Group Script

Contains options that enable you to save a script that reproduces the platform report for all levels of a By variable to several destinations. Available only when a By variable is specified in the launch window.
