I would like to request help for a problem with panels.
What I have is this:
I have a list of observations that indicate "events". These have a date
and a subject ID.
Using "collapse" I have turned them into a panel with ID and time (years).
When the event has not occurred within a year, the observation year does
not exist. That is, there are gaps in the panel.
I would like to add observation years for each ID with the value "0" to
the event, when there is no event - essentially to close the gaps.
As my original dataset with events is the only relevant source of
information about the events, the values should be zeroes.
I have tried to read about tsappend, but I could not figure out how to
use this command for this end.
