Dear experts,
I would like to use randomise to carry out group comparisons for my data.
I have 15 subjects with pre- and post- treatment, therefore, I follow the instructions and setup a paired t-test design (http://www.fmrib.ox.ac.uk/fsl/feat5/detail.html#PairedTwoGroupDifference). In addition to this, I would like to include their performance as an additional EV, and I found the example here: http://www.fmrib.ox.ac.uk/fsl/feat5/detail.html#SingleGroupAveragewithAdditionalCovariate. But I am a little bit confused on how to bring these two together...
Could someone give me a hint on how to draw the paired t-test design matrix with an additional EV?
Thanks!
Monica
