Dear all,
I want to replace a variable's missing value with its first nonmissing
value, how can I realize this? I read the FAQ at
http://www.stata.com/support/faqs/data-management/replacing-missing-values/,
but there is no example for my case.
My data structure is like :
_n myvar
1 .
2 .
3 .
4 1
5 2
6 6
7 .
After replacement, I want to get data as:
_n myvar
1 1
2 1
3 1
4 1
5 2
6 6
7 1
Thank you.
Best,
Sharon
