Suppose the 1st singular value, S1,
is by far the largest and hence it’s
associated eigenimage explains “most”
of what is common among all the images.
To see the extent, (S1E1*), to which this eigenimage is
present in each individual scan, we need only examine the
temporal weight of the nth scan (nT1). If this eigenimage is
“relevant” to our scan conditions, its contribution to
each scan condition (nT1 values) should vary in a meaningful way
across scan conditions.
