Dear crowd,
I have a rather "simple" problem which I cannot solve, however.
I have panet data and want to run a bunch of regressions. One regression is supposed to entail data from the years 1998-2004, the other from 1996-2006, another one 1993 to 2009, and so on.
How can I run these "IF" regressions?
Thanks a lot in advance!
Barbara
