Hi everyone, I wonder why the confidence intervals (variance estimates) are slightly different when I run the exact same proc surveylogistic syntax using SAS 9.4 and SAS 9.3. For example: proc surveylogistic data= abc varmethod= BRR; weight WGT_FULL; repweights bsw1-bsw500 / df =24; class sex (ref= '1') / param = ref; model SLP=sex; run; The confidence intervals are slightly wider when I used SAS 9.4. Are there any differences between the two versions for this procedure?? I can't seem to find the information anywhere else. Thanks!
