st: RE: time and date series
In Stata, and indeed elsewhere, you can't
have it both ways. The definition of a panel
implies (a) identifiable individuals and (b)
at most one observation for each time unit
and individual. Other data structures cannot
be mapped into that without sacrificing something.
