In such data, the data blocks corre- spond to the different subjects. Both the observations in the data blocks and the data blocks themselves can be either fixed or random. For instance, in the case of multioccasion–multisubject data, the data blocks are considered fixed when the researcher...
It is also possible to use sum contrasts, which code one of the conditions as -1 and the other as +1, effectively ‘centering’ the effects at the grand mean (GM, i.e., the mean of the two group means). Here, we rescale the contrast to values of -0.5 and +0.5, which makes ...
