First of all, congratulations on your wonderful work on this platform.
Although I have read several posts about weights for analyzing IPUMS_HNIS data, I am not sure I have found an answer to my specific question.
I plan to perform a analysis with mortality as an outcome (Cox). In this case, I know I have to use MORTWT when analyzing mortality in conjunction with variables originally included in the NHIS person files, or MORTWTSA when analyzing mortality in conjunction with variables from NHIS adult files. However, my main exposure variable is in the adult files, but most of co-variables are from the person files. I think that, in the case that variables come from two different types of files (person and adult files), the most restrictive weight should be used. If I am correct, should I use MORTWTSA as the weight for all analyzes? Finally, to calculate the data for the descriptive table (eg, percentage by sex, mean age, etc.), should I also use the MORTWTSA weight, or the PERWEIGHT or SAMPWEIGHT weights depending if each variable is from the person files or from the adult files, respectively?
Thank you very much in advance. Best regards,
