MAN Analysis--Wizard Between Design - Custom Between Design Tab
Select the Custom between design tab of the MAN Analysis Wizard Between Design dialog box to access options to select the specific effects for the selected variables that are to be included in the model. Note that categorical predictor variables that are not selected into the Effects in between design list, but were selected via the Variables button in the MAN Analysis Wizard Between Design dialog box, will automatically be dropped from the analysis.
Effects can be specified in the following manner:
- Select the Categorical variables in the Predictor variables group box by clicking on them; select multiple variables by holding down the CTRL key while clicking on the respective variables; select a list of consecutive variables by dragging the mouse pointer over the list.
- Click on the desired action in the Method box.
The specified effects will automatically be listed in the Effects in between design group box. You can further edit the effects in the Effects in between design group box by using the following options:
Element Name | Description |
---|---|
Predictor variables.; Categorical. | The Predictor variables group box contains the Categorical variables selected for the current analysis. Select the variables you want to include in the design. |
Method | The Method group box contains the available options for including the selected variables as effects in the design. Some options may only be available if the appropriate number were chosen in the respective Predictor variables group box. For a discussion of various designs (e.g., factorial, repeated, etc), see the General ANOVA/MANOVA - Quick tab topic. |
Add | Click the Add button to add the main effect(s) for the selected categorical predictor variable(s) to the list of Effects in the design. |
Full cross | Click the Full cross button to create the respective interaction term for all selected variables (e.g., Gender*Group*Time). Note that this button is only available if two or more categorical predictor variables are selected. |
Full factorial | Click the Full factorial button to create a full factorial design for the selected variables (e.g., Group Gender Time Group*Gender Group*Time Gender*Time Group*Gender*Time). Note that this button is only available if two or more categorical variables are selected. |
Fact. to deg. | Click the Fact. to deg. (Factorial to degree) button to create a factorial design (up to the degree specified in the Degree field) for the selected variables (e.g., Group Gender Time Group*Gender Group*Time Gender*Time). Note that this button is only available if two or more categorical predictor variables are selected. |
Degree | Use the Degree field in conjunction with the Fact. to deg. option; see descriptions above. |
Effects in between design | The Effects in between design group box shows the effects currently in the design. These effects can further be edited via the following options: |
Cross | Click the Cross button to cross two effects currently selected in the Effects in between design group box; e.g. if two effects A and B(C) are currently highlighted, then Cross will add the term A*B(C) to the effects in the design. If more or fewer than two effects are selected, this option is not available. |
Remove | Click the Remove button to remove the selected effect(s) from the Effects in between design group box. |
Clear all | Click the Clear all button to remove (clear) all effects from the Effects in between design group box. |
Reordering effects | To reorder the effects in the Effects in the design group box, first select them (e.g., click on the effect or list of effects), then move the mouse cursor to the desired location in the list, and when the mouse cursor changes to the insertion bar , click the mouse button to move the selected effects. |
Complex designs | To specify
nested designs,
designs for mixtures,
response surface designs, etc., use the facilities of GLM.
For alternative ways of specifying designs in ANOVA/MANOVA, see Methods for Specifying Designs. |
