chapter_11_table_1

For the present data set, six individuals were observed under two 
different conditions. The question of interest is: 'does the mean 
of the scores in Condition 1 differ from the mean of the scores
in Condition 2.' 
 
To perform the repeated measures analysis, PROC GLM is used. On the MODEL
statement line the repeated factors are placed on the left side of the equals
sign. Notice that for the present analysis no covariates or group 
identifiers are included on the right side of the equal sign. However,
/NOUNI is included, which simply tells SAS not to perform separate
univariate analyses on each level of the condition (ycond1 and ycond2 here).
The REPEATED line below the model statement tells SAS what factor is 
being repeated (this can be named anything). The results of this 
analysis match those given in Table 11.3. 

Note that by default results for the multivariate repeated measures
analysis as well as the results for univariate repeated measures
analysis are given. At the present time we are only interested 
in the univariate analyses (even though they are equivalent in 
this particular instance). 

Further note that because there are only two levels of the 
repeated factor, a paired samples t test could have been performed.
