Dear all,
I am trying to study if the SBT(a phenotype) change from timepoint 3 to
timepoint 7 are different for case and control. The condition has two
levels(case vs control) and timepoint have three levels(0,3,7), I need to
write a contrast statement,here is my code:
contrast 'SBT change over time for case vs control '
condition*timepoint 0 -0.5 0.5 0 0.5 -0.5 ;
in the contrast statement, I also have to include the main effects.
Could you tell me for my case how should I write the sas code including both
main effects and interaction effects? Thank you very much!
