Hello,
I'm using SAS 9.4 full edition. I am trying to do a median regression analysis. I pasted the base code below but it's not working. I also pasted the error messages below.
proc quantreg ci=resampling;
class VARIABLE1 (param=ref ref='CONTROL');
model COST=VARIABLE1 VARIABLE2 VARIABLE3 / quantile=0.25 0.5 0.75;
run;
ERROR 22-322: Syntax error, expecting one of the following: a name, ;, -, /, :, _ALL_,
_CHARACTER_, _CHAR_, _NUMERIC_.
ERROR 76-322: Syntax error, statement will be ignored.
Thanks very much in advance for the help!

Different procedures have different CLASS statements due to historical evolution. You are specifying options that do not exist in quantreg. I provide a link to the syntax.
Thanks - the manual doesn't mention how to program the reference group though using class statement in proc quantreg. Would someone mind posting sample code?

You can't. You can change the level in a data step. Prepend a 'Z' or something to the level you want to be the last level so it sorts last.
