If it is only one subject and you have no continuous variables, you can do it that way. If you have continuous variables, you will need to use DOSS (different-offset same slope) to force the slopes to be the same across classes (because you can't compute a slope from a single data point)

Thank you Douglas. That’s much clearer. I do however,  have a subject without a gender disclosure. Would I set up my class and contrasts as:

5 classes: PatentientsMale, PatientsFemale, HCMale, HCFemale, HCNa

then use contrast [0.5 0.5 -0.33 -0.33 -0.33 0 0 0 0 0 ...]?

Best,

Liliana
