I am trying to link individuals across February 2020 and April 2020 basic monthly CPS samples. I want to perform a time series analysis for changes in individuals’ employment from T1 (Feb. 2020) to T2 (April 2020).
I downloaded the samples separately and then tried to merge them using the command merge 1:1 CPSIDP using _data file with Stata 16. However, the results only show me “matched (3)” in one month. And when I scroll down the data file to April, the merge variable says using “2 only.” Any suggestions would be greatly appreciated!
