I am working with a matched case control dataset and I am running the following proc logistic procedure.
proc logistic descending data = data;
strata newgroup;
model new_case = exp;
run;
newgroup is the matching variable.
new_case is the binary outcome variable (1/0).
exp is the binary exposure variable (1/0).
I am trying to replicate results that my coworker did in stata.
So my first question is:
- How can I run logistic regression in sas with robust or cluster standard errors?
- What kind of standard errors does proc logistic use? (I am assuming it is not robust or cluster)
My apologies if these are really stupid questions!
