All of the weights in PASS are so-called probability weights: the weight of a household or a person is equivalent to the reciprocal value of its/his/her inclusion probability (adjusted by non-response modelling and calibration). In Stata, starting with version 9, probability weights have to be set using the surveyset command (see Stata Corp 2007). However, surveyset not only has the purpose of defining the weights to be used, but also of defining the aspects of the survey design that have an impact on the standard errors.
