External Email - Use Caution
Dear experts,
I am using FS 6.0 for some studies. I want to calculate the thickness
difference between males and females in two group, Young group and Old group.
In DODS model:
The first step: creat a FSDG file:
GroupDescriptorFile 2
Title Tutorial
Class Young, Female
Class Old, Male
Variables education
Input P01 Young Female 11
Input P02 Old Male 9
Input P03 Young Male 10
The second step: creat contrast matrix
1 -1 -1 1 0 0 0 0
Is it right? I am not sure if the FSDG file and contrast file are right.
Waiting for you to solve my problem.
Thanks for your attention and help.
Sincerely,
Zheng
