Good morning,
I'm a new SAS user, I'm using SAS Vyia for learners.
I have a dataset and I found out that most of the missing values are classified as "unknown" instead of the usual "NAs".
Should I change them with a code or does SAS recognize the fact that "unknown" is a missed value?
If I should change and replace their names in NAs, how may I do?
Please see your classmates question here:
