I have data set:

PX               BMI     SMOKE

Patient_1    YES     NO

Patient_1     NO      YES

 

And I want:

PX               BMI     SMOKE

Patient_1    YES     YES

 

Is there a way to make Patient_1 in just one row instead of having multiple rows?

Is it only Yes/No that you're comparing, or are there other variables that may have other ranges?

 

If it's Yes/No you can use SQL and MAX function. This will work because Yes is alphabetically after No. If you have other values you'll need a different approach.

 

 

proc sql;
create table want as
select px, max(bmi) as bmi, max(smoke) as smoke
from have
group by px;
quit;
