Dear SPM users
I am wondering how to model my quantitative (BP or SUV) receptor data in SPM. Should I use "Grand mean scaling" under Design and/or Global normalization? If so, proportional or Ancova?
Do I need to normalize if the data input is already quantitative?
My design is a paired t-test with a control group and an intervention group.
I appreciate any input regarding my question.
Thank you,
Kathy
