I keep coming to a dead end when trying to find out how to do the following in Proc Tabulate. I would like to create the percentages as shown in the attached table. You will see that the treatment counts should be calculated as a percentage of the number of patients in each region.
If anyone could help I would be really happy. I've been trying to solve this for a long time!
Thanks very much in advance!
Here's the code I have with the variable names.
data all1; set all; by patno; if first.patno then pat_cnt = 1; run;
proc tabulate data = all1; class grp trt region; var pat_cnt; tables pat_cnt (grp * trt), region; run;
