Hi,
My understanding is that absent endogenous variables and singletons,
xtivreg2 & xtreg should give identical results. Yet, I get different
std. errors and as a result t-stats, (coefficients are identical).
Both regs are using the same exact number of observations. Including
the "small" option for xtivreg does not make a difference.
Why?
Thanks!
