Dear all,
I have 2 quick questions about demeaning:
1. Does 'demeaning' take the mean of the regressor time series and subtract
it from the time series? Or does it take the mean of the regressor values,
and subtract it from the time points where regressor values are specified?
2. Does demean take place before convolution with HRF or after? Would this
make a difference?
thanks
