Workspace Node: Boosted Regression Trees - Results - Prediction Tab

In the Boosted Regression Trees workspace node dialog box, under the Results heading, select the Prediction tab to access the following options.

Element Name Description
Sample Select an option button in this group box to specify for which type of sample to compute the predicted and residual statistics.
Analysis Only those observations that were used to compute the current results (i.e., build the current set of trees) will be displayed.
Prediction All cases that have valid data for the predictor variables, but missing data for the dependent variable will be displayed.
Test set All observations that were not used to compute the current results, but have valid data for all predictor and dependent variables will be displayed.
All samples Display and plot predicted and residual values for all observations.
Predicted values Select this check box to produce a spreadsheet showing the observed and predicted values for the current solution. If the response variable is categorical, the results will also indicate the observed classifications, predicted classifications, and posterior prediction probabilities for each response category. If the response variable is continuous, the spreadsheet will contain the predicted and residual values for each observation. Note that plots of predicted and residual values only apply to (are available for) analyses involving a continuous dependent variable.
Predicted vs. residuals Select this check box to produce a scatterplot of the predicted values and the corresponding residuals for the dependent variable.
Observed vs. predicted Select this check box to produce a scatterplot of the observed and the predicted values.
Observed vs. residuals Select this check box to produce a scatterplot of the observed values and the corresponding residuals for the continuous dependent variable.
Probability plot of residuals Select this check box to produce a normal probability plot of residuals for the continuous dependent variable.
Histogram of Residuals Select this check box to produce a histogram of residuals.
