They are ignored by: tag, group, nunique, max, min, first, last, firstnm, lastnm. All other functions do not allow weights. WebTo use replicate weights in Stata, you first must describe the survey to using the svyset command: svyset [iw=perwgt], sdr (pwgtp1-pwgtp80) vce (sdr) The use of the replicate weights allows the data to be treated as one strata, so no Primary Sampling Unit (PSU) needs to be specified. The full sample weight, perwgt, must be identified.
