I am facing a question regarding sampling weight in the IPUMS USA data. I know that I can apply sampling weights in regressions using built in commands in various softwares. I wanted to ask if there is a possibility to manually apply sampling weights to each observation and create a weighted sample, which would then not require to use the perwt variable. For instance, multiplying the variable by sampling weight, or dividing it by sampling weight or any other such operation. I would be thankful for a response.
