I think this macro is extremely useful! It produces summary statistics (mean/median/min/max/counts) and p-values between two groups of a class variable.<BR /> <BR /> My question for anyone who has used it is the following:<BR /> <BR /> What if there is a subgroup analysis someone wants to do? I see this is awesome for getting descriptive statistics including p-values for a class variable with varying levels. How about if I want one main class variable (like Case and Control) and subgroups (like Old/Young)? Does this macro support this type of analysis?<BR /> <BR /> Thank you so very much!<BR /> Monica<BR /> <BR /> The macro can be found:<BR /> <A href="http://mayoresearch.mayo.edu/mayo/research/biostat/upload/summary.sas" target="_blank">http://mayoresearch.mayo.edu/mayo/research/biostat/upload/summary.sas</A> Wed, 08 Dec 2010 19:37:28 GMT https://communities.sas.com/t5/SAS-Programming/Summary-Macro-from-the-Mayo-Clinic/m-p/47183#M9750 deleted_user 2010-12-08T19:37:28Z https://communities.sas.com/t5/SAS-Programming/Summary-Macro-from-the-Mayo-Clinic/m-p/47184#M9751 Not directly.
