Dear SAS experts
What would be the proper way to adjust the effects of the nuisance covariates in quantile regression?
Y=Dependent var
X=Independent var
Nuisance covariates=Age, Edu
Thanks for considering my request.
PS. SAS 9.4 on PC
Best regards

1. Are the AGE and EDU variables continuous or categorical?
2. Are you asking this question BEFORE the data are collected or after? In other words, are you asking about how to set up an experimental design to control for age and education level as part of measuring response? Or do you have the data and you want to incorporate AGE and EDU into the model?
