I’ve noticed that the top-codes have changed for some variables in the ASEC files compared to the same variables in the data downloaded a few years ago, but without a change in the documentation.
For example, when I downloaded the data a few years ago, the variable incasist had a max value (excluding 99,999) of 99,997; this was the stated top-code in the documentation.
However, in the current version of the data, the top-code appears to have been changed to 9,999,997, which seems way less appropriate given the distribution of the non-top-coded observations. In addition, the mean of the non-top-coded data are identical in the older version and the new version, so the only thing that has changed are 4 observations whose top-code went from 99,997 to 9,999,997.
Are we meant to replace those top-coded values with 99,997 and treat that as a mistake?
Thanks very much for your help!
