What does "fixed effects using binary" mean? What are d04 and d05? By
MCO do you mean "Monte Carlo Optimization" to estimate numerical
integration via sampling?
The test that all FE are 0, or var(u_i)=0, is reported by -xtreg, fe-
as a matter of course, I believe, and available as e(F_f) after
estimation.
Can you restate your problem in terms of available data, e.g. start with
webuse grunfeld, clear
or the like?
