Throw in a -sort- after -expand- to make this work:
***********
...
expand 3
sort id
inp str10 name
...
***********

-sort-ing allocates the name to the end, so you can pick it up there...
***********
clear*
set obs 5
gen byte id=_n
expand 3
inp str10 name
""
Nick

l, sepby(id)
bys id (name): replace name=name[_N]
l, sepby(id)

Subject: st: replace blank string values
I have a dataset which is a panel: id, year where id is the numeric
value the individual.
I also have the name of the individual, however, for some
observations, the name is missing.
How do I go about replacing the missing values for name?
One way that works is
sort id year
by id: replace name = name[_n + 1] if name == "" & name[_n + 1] ~= ""
by id: replace name = name[_n + 1] if name == "" & name[_n + 1] ~= ""
...
by id: replace name = name[_n + 1] if name == "" & name[_n + 1] ~= ""
However, is there a more efficient way of doing this, say using egen?
Richard
