Onderwerp: [SPM] general linear model question
Dear SPMers:
I am geting confused about the genreal linear model. I
couldn't find the documentation except that I am
waiting for Dr Friston's papers from Library request.
for example, two-sample t-tests, why we couldn't do
t-tests voxel-by-voxel directly for two groups? what
is the logic behind to establish a linear model like
X=Gb+e?
here X is the signal intensity? what does b mean here?
thanks in advance
Weiying
