GRM Quick Specs - Quick Tab
Select the Quick tab of the GRM Quick Specs dialog box to access the options described here. The specific options that are available in this dialog box depend on the Type of analysis selected on the General Regression Models Startup Panel - Quick tab.
| Element Name | Description |
|---|---|
| Variables | Click the Variables button to display the standard variable selection dialog box. Depending on the Type of analysis selected on the GRM Startup Panel - Quick tab, STATISTICA will prompt you to select one or more dependent variables, one or more categorical predictor variables (grouping variables or factors in the design), and/or one or more continuous predictor variables (covariates). For example, if you select Simple regression from the GRM Startup Panel - Quick tab, you will be prompted to enter one or more dependent variables and a single predictor variable; if you select General linear models, you will be prompted to specify dependent variables and both (optionally) categorical and/or continuous predictor variable lists. For details concerning different types of designs and the distinction between continuous and categorical predictor variables, see the Introductory Overview. |
| Factor codes | Click the Factor codes button to display the Select Codes for Indep. Vars (Factors) dialog box, which contains options to select the codes identifying the levels for the categorical predictor variables (grouping variables). Codes must be integer values or text labels (but can be dates, times, etc.), and at least two codes must be specified for each categorical predictor variable. This option is only available if categorical predictor variables (grouping variables) were specified for the current analysis via the Variables button (see above). |
| Between effects | Click the Between effects button to display various dialog boxes, depending on the Type of analysis selected on the
GRM Startup Panel - Quick tab. If
Factorial regression or
Factorial ANOVA is selected, the
GLM Between Effects (Factorial Design) dialog box will be displayed. If
Polynomial regression is selected, the
GLM Between Effects (Polynomial Regression) dialog box will be displayed. If
General linear models is selected, the
GRM Between Effects dialog box will be displayed. These dialog boxes are used to specify a custom design for the categorical and continuous predictor variables.
This option is only available if the Type of analysis selected on the GRM Startup Panel - Quick tab involves a complex design for the chosen categorical and/or continuous predictor variables. If you select a simple design, such as Simple regression, then this option may not be available. If you decide that the design for the categorical and/or continuous predictor variables needs to be customized, you can either click the Syntax editor button (in the lower-right corner of the GRM Quick Specs dialog box) to further customize the model via GRM Syntax, or you can return to the GRM Startup Panel - Quick tab and select General linear models as the Type of analysis. If the variable selection includes multiple categorical variables, the default design is main effects only. This is reflected in the text displayed in the text box next to the Between effects button. For alternative ways of specifying designs in GRM, see Methods for Specifying Designs. See also GRM - Index. |
