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.
Undefined values are values that are not in your value set but that have a value (unlike not applicable values). So say you have a value set for Sex with values 1 for Male and 2 for Female, then codes 0 and 3 - 9 would be listed in the Undefined category.
