Folks,
Very sorry to bother you on this tricky question.
My data is not a typical longitudinal (panel) data: they are not
observations on the same subjects across 30 years, but observations on
similar subjects across 30 years (like different persons in different
years).
What do you mean by "similar"? Were subjects actually matched across
time with similar counterparts?
I'm guessing you mean you have successive cross-sections, e.g. some
sort of study that was done 30 straight years, each time with a
different sample. In the US, this would be like the General Social Survey.
Another issue is, do you have the same measures across time, or are
there a lot of changes from one year to the next?
If you can clarify exactly what it is you have, that may help.
