Good afternoon SPM Users!
I have a little problem with the SPM results interpretation. I refer to
the Statistics results.
I put p<0.001 uncorrelated. The High Threshold F have a determined
value. I understand that this value is the value with that is
acomplished the p-value<0.001.
The statistics SPM report have three parts (set level, cluster level and
peak level.
In the case of cluster level what is the meaning of PFWE-corr, QFDR-corr
y Punc. I understand that PWE-corr would be the value of the p-value if
we apllied a FWE correction, the same with the QFDR, in this case with
False Detection Rate, but I don't understand well the meaning of the
p-value uncorrelated. I believe that is the p-value in the cluster. But
what is the meaning when this value is 0.000?.
I probe for example with p<0.02 (i increase the signal) but in theory i
have less accuracy in my results, but in this case the pfwe and qfdr and
punc are better. What is the meaning of this?
Thanks in advance!
