General Discriminant Analysis (GDA) Models Syntax Editor

Select General discriminant analysis in the Type of analysis list and Analysis syntax editor in the Specification method list on the General Discriminant Analysis (GDA) Models Startup Panel - Quick tab. Then click the OK button on the General Discriminant Analysis (GDA) Models Startup Panel to display the General Discriminant Analysis (GDA) Models Syntax Editor dialog. This dialog contains two tabs: Keywords and Specifications. The Keywords tab and the Specifications tab allow you to click on the respective buttons to insert them in the Analysis syntax edit field, at the current location of the cursor. The available keywords and specifications can also be typed directly into the Analysis syntax edit field. Note that this dialog will also be displayed if you click the Syntax editor button on the GDA Quick Specs or the GDA Models Wizard Extended Options dialogs.

Element Name Description
Analysis syntax Enter command syntax into the Analysis syntax edit field to completely specify the design, as well as various parameters that are used in the computations.
OK (Run) Click the OK (Run) button to begin the computations, and display the GDA Models Results dialog.
Cancel Click the Cancel button to return to the General Discriminant Analysis (GDA) Models Startup Panel, ignoring any changes that you have made on this dialog
< Back Click the < Back button to move back to the GDA Quick Specs dialog or the GDA Models Wizard Extended Options dialog (depending on the manner in which the GDA Models Syntax Editor dialog was displayed). Note when you click the < Back button on the GDA Models Syntax Editor dialog after introducing additional customizations, those customizations done in the GDA Models Syntax Editor dialog will not be translated "back" to the Quick specs dialog or the Analysis Wizard dialogs.
Options Click the Options button to display the Options menu.
  Cut, Copy, Paste Use the standard Cut, Copy, and Paste editing operations in the Analysis syntax edit field; these operations can be accessed by clicking the respective buttons, or via the standard keyboard shortcuts. For details, refer to the description of the Edit menu.
Open Click the Open button to display the standard Open File dialog, which is used to open previously saved text (program syntax) files.
Save As Click the Save As button to display the standard Save As dialog, which is used to save the current Analysis syntax to a text file. Those text files can be edited by practically all text editing and word processing programs.

Note: GDA, GRM and GLM syntax conventions. The GDA syntax conventions are essentially identical to the GLM syntax conventions and the GRM syntax conventions (see General Linear Models (GLM), and General Regression Models (GRM), with only a few additions and omissions relating to the specification of the categorical dependent variable (for discriminant analyses). For details about most model building syntax, you can refer to the GRM syntax conventions. Note that the Generalized Linear/Nonlinear Models (GLZ) and General Partial Least Squares Models (PLS) modules also use similar syntax, with sets of additional keywords (options) that are specific to those particular applications. See GDA Syntax Overview and GDA Syntax Examples for further details.

Note: using Quick specs dialog to write the syntax. In practically all cases, the most efficient way to write GDA syntax is to use the GDA Quick Specs dialog. Specifically, from the General Discriminant Analysis (GDA) Models Startup Panel - Quick tab, select the desired analysis in the Type of analysis list, and Quick specs dialog as the Specification method; then click OK on the Startup Panel to display the respective GDA Quick Specs dialog. Select your design via the GDA Quick Specs dialog and then click the Syntax Editor button on the GDA Quick Specs dialog. All current specifications (e.g., variable selections, design specifications) selected on the GDA Quick Specs dialog will automatically be transferred (translated) to the syntax editor, and can be further modified or saved.
