Imputing missing final weights for Waves 2-4

Hello, I am doing a longitudinal analysis in which I have merged together Waves 1-4 data and transposed the data to fit a "long" dataset form (example below). I am following the original Wave 1 adult and youth cohort through to Wave 4.

PERSONID                    WAVE        FINALWEIGHT

1                                     1               1234.4

1                                     2               3948.4

1                                     3               5984.1

1                                     4               MISSING

.......

Although every PERSONID in Wave 1 has a final weight, there are some missing final weights for Waves 2-4. It appears the final weight changes for each PERSONID through the waves. So, is there a way to impute the missing final weights?

Thanks!
