Dear political methodologists,
I am a phd student at the LSE who seeks some (simple) help in STATA.
I used the reshape command because I need to run a conditional logit model (also called mixed logit, Mc Fadden conditional Model, Luce model...you name it)
the data I have now looks like this (where dv is my dep variable)
ID DV ref
1 a 1
1 . 2
1 . 3
2 b 1
2 . 2
2 . 3
3 a 1
3 . 2
3 . 3
4 c 1
4 . 2
4 . 3
.
.
.
What I want to do is to fill those missing data with a, b, or c (order does not matter) depending on the data available (i.e b, and c if I have a, a and b if I have c, a and c, if I have b). In other words make it look like the following:
ID DV
1 a
1 "b"or "c"
1 "c" "b"
2 b
2 "a"or "c"
2 "c" "a"
3 a
3 "b" or "c"
3 "c" "b"
4 c
4 "a"or "b"
4 "b" "a"
. .
. .
. .
thank you very much for your help!
