Loop does not end

[Eymen Akin]

Hello everyone,

I am a beginner user of stata and was trying to create a loop to fill the missing values of a variable. To do that I used stored data in r(N). However the loop should conclude at some point but it does not end at all.

count if missing(unemplength)
return list, all

while `r(N)' >= 1 {
replace unemplength = unemplength[_n+1] if missing(unemplength)
count if missing(unemplength)
return list, all
}

This is my relevant part of the code. r(N) should become 0 at some point but it gets stuck at 8 somehow. I could not figure out what is wrong. Any help is appreciated!

Do you have panel data?

The technique of reversing time discussed at https://www.stata.com/support/faqs/d...issing-values/ may be a better way to do what I think you are trying to do.
