Hello All,
I am looking for a way to test for unit roots with a panel regression. The
problem is that I have an unbalanced panel and a version of Stata that does
not support -xtfisher-. I tried -ipshin- or -madfuller-, but they all don't
seem to work with unbalanced panels. Is -xtfisher- the only option that
works with unbalanced panels?
Thanks,
Cordula
