Dear all,
A question with regard to scaling of parametric regressors.
I have 3 parametric regressors that occupy different time points during a trial. The range of
values between the regressors differ. One regressor has range approx. [-1,1] with mean at
0, the second regressor has range [-3,3], and the third regressor [-5,5].
What would be the correct way to re-scale them so I don't have to worry about scaling
problems when running the GLM?
thanks!
