'''`-svyset-`''' declares a survey design.

<<TableOfContents>>

----



== Usage ==

The `-svyset-` declares a survey design. Subsequent estimation commands prefixed by [[Stata/Svy|-svy-]] will be adjusted to take this design into account.

Generally the command should be used as:

{{{
svyset CLUSTER [pweight=WT], strata(STRATA) vce(linearize) singleunit(centered)
}}}

If a PSU is not specified (as above: `CLUSTER`), then `_n` is implicitly used. Which is to say, it declares a single-stage sample design.

svyset house [pweight = wt], strata(eth)
