Hello
I am anlyzing FA and white matter volume and age using multiple regression on TBSS.
I have a plan to analysis below
Dependent variable = age, white matter volume
Independent variable = FA
Covariate = sex
But I could not make GLM model.
I want to know which number do I have to put in EV and Contrast.
Would you please let me know how can I do that ?
EV = 4
1 = Group
2= age
3 = white matter volume
4 = sex
Contrast
Group = 0
age = -1
white matter volume = 1
sex = -1 (?)
is that right ?
Thank you so much
