Does anyone know how to filling this missing values? I have information to fill, but I don't know how to locate these three and then assign, as other variables are the same.
if athlete="" then do;
How could I do if three missing Athletes have different age?
You need to provide some information on what you are doing I can't guess. Post test data in the form of a datastep, post example output that you want, explain the logic between the two.
The first one is my results, there are three missing value. The second is the information. I need to find the three and three them up.
And how do I know that row 4009 should contain <insert correct data>? And how to know the row 4010 should contain <insert correct data>?
