PRINT Subcommand (MANOVA: Repeated Measures command)

The following additional specifications on PRINT are useful in repeated measures analysis:

SIGNIF(AVERF). Averaged F tests for use with repeated measures. This is the default display in repeated measures analysis. The averaged F tests in the multivariate setup for repeated measures are equivalent to the univariate (or split-plot or mixed-model) approach to repeated measures.

SIGNIF(AVONLY). Only the averaged F test for repeated measures. AVONLY produces the same output as AVERF and suppresses all other SIGNIF output.

SIGNIF(HF). The Huynh-Feldt corrected significance values for averaged univariate F tests.

SIGNIF(GG). The Greenhouse-Geisser corrected significance values for averaged univariate F tests.

SIGNIF(EFSIZE). The effect size for the univariate F and t tests.

• The keywords AVERF and AVONLY are mutually exclusive.
• When you request repeated measures analysis with the WSFACTORS subcommand, the default display includes SIGNIF(AVERF) but does not include the usual SIGNIF(UNIV).
• The averaged F tests are appropriate in repeated measures because the dependent variables that are averaged actually represent contrasts of the WSFACTOR variables. When the analysis is not doubly multivariate, as discussed above, you can specify PRINT=SIGNIF(UNIV) to obtain significance tests for each degree of freedom, just as in univariate MANOVA.
