Hi all, 

 

I have a total leisure time physical activity (MVPA) as a continues variable. I am trying to create a new MVPA variable that is in tertiles. 


So far this is what I have done

 

proc rank data = recode5;
ranks groups = 3;
var mvpa;
ranks mvpa_tert;
run;

 

But this code is not working....

 

Any help and guidance is greatly appreciated! 

 

Thank you!

You didn't specify an output data set in the PROC RANKS statement so the data created is probably called DATA1 or something. 

check your log.

Thank you for the advice. The code seems to run. The  log is not producing any errors. However when I tried to run cross tabulations is saying that  mvpa_tert (my new categorical variable) not found. 

 

Thank you!

I think you have a semicolon too early.

Doesn't work is awful vague.

Are there errors in the log?: Post the code and log in a code box opened with the {i} to maintain formatting of error messages.

No output? Post any log in a code box.

Unexpected output? Provide input data in the form of a dataset, the actual results and the expected results. Data should be in the form of a data step. Instructions here: https://communities.sas.com/t5/SAS-Communities-Library/How-to-create-a-data-step-version-of-your-dat... will show how to turn an existing SAS data set into data step code that can be pasted into a forum code box using the {i} icon or attached as text to show exactly what you have and that we can test code against.

 

proc rank data = recode5;
ranks groups = 3;
var mvpa;
ranks mvpa_tert;
run;

 

Groups is an option that goes on the Proc Rank statement, not as you have it her

 

Try

proc rank data = recode5
    groups = 3
;
   var mvpa;
   ranks mvpa_tert;
run;

You likely didn't run it on the new file created. SAS will automatically supply a name for the file if you don't.

Try:

proc rank data = recode5 out=want groups = 3;
  var mvpa;
  ranks mvpa_tert;
run;

and then do your analyst on file want
