Quantile Regression: Controlling for the effects of the nuisance covariates

[Larry103]

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?

1. Continuous variables

2. After the data

Thanks
