Re: st: sampling weight in --sum,--fsum
Dear Man Jia,
see help svy_estimation. With survey data, you can estimate mean,
proportion, ratio and total.
Using sampling weights is important to get the point estimates right.
If you ignore strata or clusters, you probably will estimate standard
errors biased (See Stata Manual SVY and others references).
