Struggeling with svydesign(). ****pgm: logistic. I did not think that there was a problem and would certainly use more replications in practice. To have Stata use the wide data structure, type: mi set wide. If IPUMS doesn't have a "complex" survey design, you can just use: mean hhincome [pw = hhwt] Or, for convenience: svyset [pw = hhwt] svy: mean hhincome svy: regress hhincome `x'. I'm currently doing some analysis with the IPUMS-USA ACS data and am looking for some advice on which weights are appropriate to use in Stata. Warning: Using if or in restrictions will often not produce correct variance estimates for subpopulations. In Stata they refer to binary outcomeswhen considering the binomial logistic regression. Stata svyset design. Stata’s sem and gsem commands fit these models: sem fits standard linear SEMs, and gsem fits generalized SEM s. For example, if a population has 10 elements and 3 are sampled at random with replacement, then the probability weight would be 10/3 = 3. SVY:LOGIT produces logistic regression models.
