Dear Listers,
Just a quick question, i appreciate any comments.
I have an unbalanced panel for several hundred firms. the maximium length
is 7 whereas the short is 1 for some of the firms. the mean length is 5.4.
I want to fit a fixed effect regression while one of my supervisor
prefers poolling regression. I don't know what kind of test can i use to
choose models between them
can u give me some suggestions?
thanks in advance
Levy Lee
