proc freq from wide data table

Posted 08-28-2019 04:18 PM (351 views)

I have data set like this. I want to know number of specimens type testtype and results.  And number of specimen type testtype and resluts by id.  Your help in this would be appreciated.

Re: proc freq from wide data table

Posted 08-28-2019 04:29 PM (342 views)  |   In reply to Dhana18

Transpose the data so there is one colldate, specimen, testype and result per record.

Then use proc freq.

 

data want; 
   set have;
   array c colldate: ;  /* alternatively Colldate1 - ColldateN */
   array s specimen: ;
   array t testtype: ;
   array r result:   ;
   /* assumes you have the same number of each*/
   do i=1 to dim(c);
      if not missing(c[i]) then do;
         colldate=c[i];
         Specimen = s[i];
         TestType = t[i];
         Result   = r[i];
         output;
      end;
   end;
   keep id colldate specimen testtype result;
run;

proc freq data=want;
   tables specimen*testtype*results/list;
   tables id*specimen*testtype*results/list;
run;

I couldn't tell if you wanted the summary as individuals or combinations. I present the combinations. Remove the * in the first tables statement to get of each variable.

You might want

tables id* (specimen testtype results)/list;

for Id by each of the other variables.

Expected output from this data? Please also provide sample data as a data step.

 

Here are instructions on how to provide sample data as a data step:
