Comparing multiple rates

BTAinRVA — Tue, 06 Oct 2015 16:06:29 GMT

I'm analyzing emergency room utilization rates at several sites and want to do a multiple comparison test. I have the raw data (ER visits and Enrollees) and was wondering if someone could suggest a way to analyze them. I'm thinking it would be a GenMod or Glimmix solution.

Thanks,

Brian

I adapted the code from here

data EDRate;
         input v e Group$;
         ln = log(e);
         datalines;
         23   155  Group1
         29  276  Group2
         54    550  Group3
         ;

 proc genmod data=EDRate;
         class Group;
         model v = Group / dist=poisson link=log offset=ln;
         lsmeans Group / ilink cl;
         run;

where v are the number of ED visits and e are the number of enrollees. Does this look like an appropriate way to analyze the data? Any helpful hints would be greatly appreciated.

Thanks,
