Hi,
To make sure my design.mat and design.con for dual regression was set up properly, is it correct to say that if I have 3 groups of total 15 subjects and want to know the differences between each group for each component then:
The Matrix would be (note that the order of subjects was no entered such that the groups where nested together):
/NumWaves 3
/NumPoints 15
/PPheights 1.000000e+00 1.000000e+00 1.000000e+00
/Matrix
0.000000e+00 0.000000e+00 1.000000e+00
0.000000e+00 1.000000e+00 0.000000e+00
0.000000e+00 0.000000e+00 1.000000e+00
0.000000e+00 0.000000e+00 1.000000e+00
0.000000e+00 1.000000e+00 0.000000e+00
0.000000e+00 0.000000e+00 1.000000e+00
1.000000e+00 0.000000e+00 0.000000e+00
1.000000e+00 0.000000e+00 0.000000e+00
0.000000e+00 1.000000e+00 0.000000e+00
0.000000e+00 1.000000e+00 0.000000e+00
0.000000e+00 1.000000e+00 0.000000e+00
1.000000e+00 0.000000e+00 0.000000e+00
1.000000e+00 0.000000e+00 0.000000e+00
0.000000e+00 1.000000e+00 0.000000e+00
1.000000e+00 0.000000e+00 0.000000e+00
AND
/ContrastName1 "Autism > Control"
/ContrastName2 "Control > Autism"
/ContrastName3 "Autism > DevDelay"
/ContrastName4 "DevDelay > Autism"
/ContrastName5 "Control > DevDelay"
/ContrastName6 "DevDelay > Control"
/NumWaves 3
/NumContrasts 6
/PPheights 1.000000e+00 1.000000e+00 1.000000e+00 1.000000e+00 1.000000e+00
1.000000e+00
/RequiredEffect 4.432 4.432 4.910 4.910 4.725 4.725
/Matrix
1.000000e+00 -1.000000e+00 0.000000e+00
-1.000000e+00 1.000000e+00 0.000000e+00
1.000000e+00 0.000000e+00 -1.000000e+00
-1.000000e+00 0.000000e+00 1.000000e+00
0.000000e+00 1.000000e+00 -1.000000e+00
0.000000e+00 -1.000000e+00 1.000000e+00
Is this correct?
Most grateful,
Varina
