Worksheet here presumably means dataset. Vector may mean vector
although I guess you really mean variable. On using Stata terminology
for maximum clarity see e.g.
http://www.stata.com/statalist/archive/2008-08/msg01258.html
Stata's commands for sampling with replacement fall mostly under the
heading of bootstrapping. However, bootstrap sampling from time
series, as here, is difficult to do without messing up the dependence
structure or invalidating any commands that depend on a prior -tsset-
or -xtset-.
