chapter_13_table_1

For the hypothetical data contained in Table 13.1, five participants 
were measured at two occasions. The question of interest is: "is there 
a difference between Time 1 and Time 2 scores?"

To perform the repeated measures analysis, PROC GLM is used. The 
analysis proceeds in the same manner as it did for the univariate
approach in Chapter 11. The repeated factors are placed on the left 
side of the equal sign. Notice that for the present analysis no 
covariates or group identifiers are included on the right side of 
the equal sign. Recall that the /NOUNI option on the model line 
means to not report tests of the univariate effects for each level 
of the time factor.

Although the univariate and multivariate repeated measures designs are
performed with the same code, the difference between the approaches 
is in the output. Whereas for the univariate approach the results were
given under 'Univariate Tests of Hypotheses for Within Subject 
Effects,' the results for the multivariate analysis are given under
the heading of 'Manova Test Criteria....'
