Jennifer--
I don't have a manual handy, but I believe the approach is to sample
panels (thus, strings of time series corresponding to the whole panel,
in your parlance) with replacement, much as the cluster option on
-bootstrap- does. Also note
(from update 06oct2006)
1. areg with option vce(bootstrap) or vce(jackknife) resampled
observations instead of the groups identified by the absorb()
variable. This has been fixed.

Hello,
It isn't clear to me what kind of sampling method the vce(bootstrap) command uses when you specify it as an option for xtreg with fixed effects with a panel. Does it use a "block bootstrap" method, i.e., drawing strings of time series from within the i() variable? If so, how long of a block does it draw? If not, how is it dealing with serial correlation? Thanks in advance for your insights. Best, Jennifer
