In the
GLM Custom Design node dialog box, under the
Results heading, select the
Custom tests tab to access options to perform tests of selected effects with a custom error term. See the GLM Examples for how this option can be used to analyze designs where not only the observations but also treatment levels are randomized (e.g., in cross-over designs; see, for example, Milliken & Johnson, 1992, Section 32.2). If you selected the
Lack of fit check box on the
GLM Custom Design - Specifications - Options tab, you can also select
Pure error as the error term for the selected effects; the pure error is computed from the sums of squares within each unique combination of treatment levels (for categorical predictors) or values (for continuous predictors).

| Effect(s) to test
|
In this list, select one or more effects to test. To select multiple effects, hold down the CTRL key and click on the respective effects; to select lists of consecutive effects, click the first effect and then hold down the SHIFT key when you click the last effect in the consecutive list.

Select this check box to produce the Custom multivariate test of significance spreadsheet.
Note: Within-subject (repeated measures) effects. If the design includes within-subject (repeated measures) factors, the resulting ANOVA or MANOVA table will also include the interactions of all within-subject (repeated measures) effects by the selected
Effect(s) to test; the error term for those effects will be the appropriate M-transformation of the
Error term for effect(s). See also the Introductory Overview for details.
