Hi, I am a firstime user of PROC SURVEYLOGISTIC and having a little trouble with relating it to PROC LOGISTIC which I normally use. Do the strata statements give similar results in both procedures.  If I have done conditional logistic regression in proc logistic using the strata statement, does the strata statement in SURVEYLOGISTIC do the same thing??
