Workspace Node: C&RT Classification - Results - Prediction Tab

In the C&RT Classification workspace node dialog box, under the Results heading, select the Prediction tab to access the following options.

Element Name Description
Sample Specify for which type of sample to compute the predicted and residual statistics (classifications).
Analysis Select this option button to plot predicted and residual values for all observations that were used to compute the current results.
Prediction Select this option button to plot all cases that have valid data for the predictor variables, but missing data for the dependent variable.
Test set Select this option button to plot all observations that were not used to compute the current results, but have valid data for all predictor and dependent variables.
Surrogate Select this option button to plot only those cases with missing data for at least one predictor variable used for splitting, if those cases were included in the analyses by using surrogate splits (see, for example, the Number of surrogates option on the Advanced tab). If these options are not available, no valid cases were found in the respective type of sample.
Predicted values Select this check box to produce a spreadsheet that will show the observed and predicted values for the current tree. If the response variable is categorical, the results will also indicate the terminal node for each case and observed classifications, predicted classifications, and posterior prediction probabilities for each response category. If the response variable is continuous, the spreadsheet will contain the terminal node ID for each case and predicted values and their standard errors for each observation. Rows are only highlighted when the prediction is incorrect. Note that plots of predicted and residual values only apply to (are available for) analyses involving a continuous dependent variable.
