Dear SPMers,
I am trying to enter covariates in a model to see their effects on gray
matter. I am interested in participants with Congenital Hypothyroidism
(CH). The covariates I want to look at are severity, treatment age, dose,
time for hormone levels to normalize, etc. I have used Gaser's toolbox to
do a two sample t-test which produced nice results. Now I want to look more
closely at the CH group.
I wonder if someone can point me in the right direction with respect to
modeling this and how to enter contrasts?
Thank you very much in advance!
