Dear experts,
I am trying to compare 2 groups with 2 covariates (age, sex) using qdec.
After loading data, design tab displays "diagnosis" in discrete, "age" and "sex" in both continuous (covariates) and nuisance factor boxes.
I just selected "diagnosis" and click "analyze". Is this a right way to remove effects by age and sex? Otherwise, do I need to check age and sex in nuisance factor box?
Thank you so much.
