Support Vector Machine Results - Quick Tab

Machine Learning Introductory Overview

Select the Quick tab of the Support Vector Machine Results dialog box to access the options described here.

Summary

Click the Summary button to create a spreadsheet containing a brief summary for the current model for the dependent variable specified for the analysis.

Model

Click the Model button to produce two spreadsheets containing the SVM support vectors and model coefficients.

Descriptive statistics

Click this button to create a spreadsheet containing statistics relating to regression and classification results (whichever is appropriate). For regression tasks, the spreadsheet will contain the means and standard deviations of the observed and predicted variables. The spreadsheet also includes the correlation coefficient. For classification tasks, two spreadsheets containing classification summary and confusion matrix will be produced.

Predictions

Use the options in this group box to compute predicted values and residuals (accuracy for classification) for the dependent variable specified in the analysis. Depending on the choice of options in the Include group box (see below), the results will include the values for the independent or predictor variables, dependent or outcome variables, predicted values, and/or residual/accuracy values.

Include

In this group box, select the type of values that you want to include in the results when displaying Predictions and Histograms (see below).

Independents. Select this check box to include the independent variable values in spreadsheets and graphs.

Dependents. Select this check box to include the dependent variable values in spreadsheets and graphs.

Predictions. Select this check box to include predicted values in spreadsheets and graphs.

Residuals (or Accuracy). Select this check box to include prediction residuals for regression (accuracy for classification) in spreadsheets and graphs.

Confidence. Select this check box to include classification confidence levels.

Predictions

Click this button to produce a spreadsheet of the variables and results selected in the Include group box.

Histograms

Click the Histograms button to create histograms of the variables and results selected in the Include group box.

Save

Click this button to display a standard variable selection dialog box, which is used to select variable(s) to be displayed together with other quantities of interest selected in the Include (see above) group box. After you select the variable(s), a spreadsheet containing the specified variable(s) will be displayed in an individual window (regardless of the settings on the Options dialog box - Output Manager tab or the Analysis/Graph Output Manager dialog box). You can, however, add the spreadsheet to a workbook or report using the or buttons, respectively. Note that in order to save the spreadsheet, you must select the spreadsheet and select Save or Save As from the File menu. This is useful if you want to use the residual values for further study with other STATISTICA analyses.
