Re: st: Bootstrapping from panel data
I think you can use bootstrapping by clusters. So if you have a firm id
that is same for all T time periods, then you can use
bsample #, cluster(firm_id)
where # = n< N. This will pick up the entire time series for any firm and
will resample firms with replacement.
