I downloaded two extracts from January 2019 (MIS 1) and April 2020 (MIS 8) and attempted to replicate lnkfw8wt using the Stata replication file available here: IPUMS CPS.
In the .do file, I replaced “mish!=4 & mish!=8” with “mish==1” since the only respondents who are eligible to match across all rotations are those in MIS 1 in January. However, the final_raked values did not match with lnkfw8wt. What else do I need to edit in the Stata replication file to create a 16-month longitudinal weight instead of the 1-month longitudinal weight? Can you share more about how lnkfw8wt was generated?
