GLZ Analysis Syntax Editor

Select General custom designs in the Type of analysis list and Analysis syntax editor in the Specification method list on the GLZ Startup Panel - Advanced tab. Then click the OK button to display the GLZ Analysis Syntax Editor, which contains two tabs: Keywords and Specifications. The Keywords tab and the Specifications tab contain buttons that, when clicked, insert the respective keywords and specifications in the Analysis syntax edit field at the location of the cursor. The available keywords and specifications can also be typed directly into the Analysis syntax edit field. Note that the Editor is also displayed when you click the Syntax editor button in the GLZ Quick Specs or the GLZ Analysis Wizard Extended Options dialog box.

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 GLZ Results dialog box.

Cancel. Click the Cancel button to return to the GLZ Startup Panel, disregarding any changes made.

< Back. Click the < Back button to move back to the GLZ Quick Specs dialog box or the GLZ Analysis Wizard Extended Options dialog box (depending on the manner in which the GLZ Analysis Syntax Editor was displayed). Note that when you click the < Back button in the GLZ Analysis Syntax Editor after introducing additional customizations, those customizations applied in the GLZ Analysis Syntax Editor will not be translated "back" to the Quick specs or the Analysis Wizard dialog box.

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 (Syntax) dialog box, which is used to open previously saved text (program syntax) files.

Save As. Click the Save As button to display the standard Save As (Syntax) dialog box, 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: GLZ and GLM syntax conventions. Overviews and examples are available for the GLZ syntax. See GLZ Syntax Overview and GLZ Syntax Examples for further details. The GLZ syntax conventions are essentially identical to the GLM syntax conventions (see the General Linear Model (GLM) module), with only a few additions and omissions relating to (1) the stepwise and best subset analyses, (2) the technical parameters for the iterative estimation procedure, and (3) the specification of models for categorical dependent (response) variables (i.e., when the distribution selected on the GLZ Startup Panel - Advanced tab is either Binomial, Multinomial, or Ordinal multinomial). Also, in GLZ you cannot specify (1) within subject (repeated-measures) designs, (2) mixed-model ANOVA and ANCOVA designs for random effects, or (3) multivariate analyses (with multiple dependent (response) variables).

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

Note that when selecting a Type of analysis, it is not necessary that your design matches exactly the chosen type of design. For example, if you want to exclude certain effects from a factorial ANOVA design, choose Factorial ANOVA from the GLZ Startup Panel - Advanced tab, specify the full factorial design, and then in the GLZ Quick Specs dialog box, click the Syntax editor button. The syntax for the full factorial design (as specified in the GLZ Quick Specs dialog box) will be written out to the syntax editor, and you can now modify the DESIGN statement to customize the design (e.g., to drop effects).
