Similarly to {help svybsamp} (if installed), the procedure respects survey design, re-sampling within different combinations of strata and PSU. Therefore using the inflation factors (pweight, see help {help weights}) the new sample can be used to get to the original "super-population". {p 4 4 2} {cmd:svybsamp2} improves considerably the speed compared to the original {cmd:svybsamp}. However, the re-samplying procedure becomes slower as the number of strata in the sample increases. {title:Examples} {hi:local i=1} {hi:while `i'<100 {c -(}} {hi:svybsamp2} {hi:qui svyreg y x1 x2} {hi:if `i'==1 {c -(}} {hi:matrix `b'=`b`i''} {hi:{c )-}} {hi:else {c -(}} {hi:matrix `b'=`b'+`b`i''} {hi:{c )-}} {hi:{c )-}} {title:Authors} {browse "http://www.econ.cam.ac.uk/phd/red29/":Rafael E.
