Undefined values in tables
Posted: September 4th, 2013, 4:43 pm
Good day,
What does it mean to have "undefined" values in a table? How can I manipulate or recode them? I've tried using the following in the tab logic but it doesn't seem to do anything.
When I wrote similar code to recode "not applicable" values it worked. So what's different about the undefined special value?

Code: Select all
recode Age => Age;
undefined => 999;
endrecode;
