Hi All,
I just wanted to confirm that FEAT only includes the non-derivative portion of the model in its
hypothesis testing and that the parameter estimate associated with temporal derivative is not
passed up to the group level. Is this correct?
If the derivative portion explains a significant portion of the variance, you can get an artifactual
decrease in the non-derivative parameter estimate? Is this right?
I recently read a paper (Calhoun et al, 2004) which suggested using a hypothesis test that includes
the parameter estimate for the derivative term. Does anyone have any opinion on this?
Finally, is the PE for the derivative saved during the FEAT analysis? Where could I find it?
thanks,
jack
