Hello,
I was wondering whether someone could please explain exactly how values are
assigned to each column of the design matrix, when a C.dat contrast vector
(e.g. [0, 0, 1, -1]) is created, in the "correlation" as opposed to in the
"intercept" types of contrasts ...
I am asking this because I have a hard time understanding how does a
contrast's automatically-created namesake folder (which includes the
keywords 'Avg'/'Diff'/'X' and 'Intercept'/'Cor'), such as
"lh-Diff-group1-group2-Cor-thickness-behaviouralMeasure", as well as its
phrasing in QDEC ("Does the thickness-age correlation differ between group1
and group2?"), exactly correspond to that C.dat vector.
Many thanks!
Tudor
