I am working with a longitudinal data; students received a degree at a certain time; I wonder how I can change all the values to 1 after degree attainment. For example, this is what my data looks like now: Id time award 1 1 . 1 2 . 1 3 1 1 4 . 1 5 . What I would like to do is to change the two missing values for time=5 and time=6 into 1. Any help is appreciated~!
