Hello,
I have a pannel data that looks like this:
Where ID is the individual ID, t is my time variable (actually 1-24, representing 2 years) and OTIF is average OTIF for that individual in that month.
I'm trying to fill in the gaps (null values) in OTIF, by creating OTIF_ADJ... using the average from last 3 months would be perfect, but I don't think it's even possible because situations like ID=1 where I don't have data from 3 months earlier to use.
So I ended up thinking about using average OTIF, using this code:
But it's not working.
I appreciate any help I can get!
Thanks!

| 1 | 3 | . |
| 1 | 4 | 1 |

Code:
bysort ID (t): generate OTIF_ADJ = OTIF if OTIF !=. bysort ID (t): replace OTIF_ADJ = mean(OTIF) if OTIF_ADJ==.
