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

In the C&RT Classification workspace node dialog box, under the Results heading, select the Classification 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.
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.
Prediction Select this option button to plot all cases that have valid data for the predictor variables, but missing data for the dependent variable.
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 vs. observed by classes Select this check box to produce a spreadsheet and a 3-D histogram of the predicted by observed classification frequencies.
Prior probabilities Select this check box to produce a spreadsheet containing the prior probabilities and the corresponding n for each class (group) in the dependent variable.
Adjusted prior probabilities Select this check box to produce a spreadsheet containing a priori probabilities for each class of the dependent variable, adjusted for the user-specified misclassification costs and the corresponding class n's. Note that this option is available only when the User-specified misclassification costs option is selected on the Specifications - Classification tab).
Misclassification cost matrix Select this check box to display a spreadsheet containing the user-specified costs of misclassifying cases or objects in each observed class of the dependent variable (columns) as another class (rows; all cost values will be 1 by default, i.e., if not altered by the user).

Options / C / W. See Common Options.

OK Click this button to accept all the specifications made in the dialog box and to close it. The analysis results are placed in the Reporting Documents workspace node after running (updating) the project.
