create dummy variables, using one as reference

Bal23 — Mon, 11 Jul 2016 19:30:41 GMT

based on what I have learned, to create dummy variables, needs to create n-1 level of variables.

however, now I need to create as one variable with several levels.

for example, for agegroup I need to have one as a reference, with each level higher being 1,2,and 3.

I remember that I used Stata to create similiar dummy variables, but do not know how to do that with SAS.

Can anybody give advice, or provide reference?

Thanks.

Last, but not least, several proc support the CLASS statement where SAS will deal with creating the dummy variables. Some Procs allow you to specify the reference level and parameterization type, but others don't so make sure to read the docs for the proc you're using.
