Find overall Newcombe risk difference confidence limit for stratified binomial outcome

cuig — Wed, 09 Aug 2017 18:55:55 GMT

I am trying to find how to get overall stratified Newcombe 95% confidence interval from FREQ, but I can only get CI for each stratum, not the overall. How do I get overall Newcombe CI?

From here, http://support.sas.com/documentation/cdl/en/procstat/67528/HTML/default/viewer.htm#procstat_freq_details63.htm, (the last few paragraph) looks like I can get Wald CI for each stratum first, and then have to manually combine each stratum Wald CI by using Mantel-Haenszel weight to get common Wald CI, and then use common Wald CI to calculate common Newcombe CI. Please help!

Thanks

Hello!

Were you able to find a solution to this question? I'm experiencing the same issue and would rather not take the time to write my own macro if the estimate is available.

Thanks!
