Would sampling with replacement, which was implied in the initial post,
really result from your procedure? Seems to me that it is w/o replacement...

Betreff: Re: st: random draw of single variable, not whole data
In addition to -bsample- and -merge-, another solution is:
clear
set obs 10
g x=rnormal()
g rnd=uniform()
egen rank=rank(rnd)
g y=x[rank]
li
drop rank
