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
you need to have four classes, young-female, young-male, old-female, old-male
