st: STATA 8,0 unit roots test for unbalanced panels

[torbjorn.dalin@econ.umu.se]

Hi,
I know this question has been posted for two years ago regarding STATA 7,0
but as far as I could see, there are no proper answers.

Do anyone know how to perform a unit roots test for an unbalanced panel in
STATA 8,0? Every test I could see needed a blanced panel.
