In the basic monthlies, why do NILFACT and WNLOOK not cover the entire nilf population? In 2018, about 12.5 percent of nilf observations do not have an answer for either WNLOOK or NILFACT.
The NILFACT universe are those who are nilf and did not provide a reason. However, there are observations who answered “nilf, other” to EMPSTAT who do not have an answer to NILFACT.
Is there any way to determine why someone is nilf for the entire nilf population? Or is the way to do this a combination of EMPSTAT, NILFACT, and WNLOOK?
