Hi Knill,
You could use -tsfill- to fill in the gaps in your time variable.

> I am trying to create a five-year moving average using data that has payments. The data contain only years where there are payments, i.e., there are no observations when payments are not made. So, for example, for the data below, I would like Stata to calculate a trailing 5-year average for firm 2177 in the year 2000 as (1000 + 0 + 500 + 1000 + 0)/5. In other words, for the non-observations, Stata should count this as a zero. This is different than the posts I saw which actually had an observation for ALL years and simply a "." If the data were a manageable size I could just go in input the observations but this is a dataset of several thousand firms. Can I still create this moving average?
