I did read them, and I just used reshape, but it is still somewhat lacking...
After I used split, I wrote "gen id = _n" and reshaped based on the
stub from the split
Now I have:
id _j stub
1 1 boy girl
1 2 boy boy
1 3 girl girl
2 1 boy girl
2 2 girl girl
2 3
3 1 boy boy
3 2
3 3
4 1 girl girl
4 2
4 3
I managed to assign a numerical value through gen and recode to each
stub's data, and relabeled it as well.
Two last questions:
There's an option for "none". That means someone did not pick "boy
girl", "boy boy" or "girl girl". As it is, right now that option would
show up under _j = 1.
id _j stub
5 1 none
5 2
5 3
What's the best way to take this into consideration/introduce this var
so that all id's have that 4th option??
How do I now re-sort/reshape this back into wide so that it shows up as:
Var1 Var2 Var3 Var4
1 boy girl boy boy girl girl
2 boy girl girl girl
3 boy boy
4 girl girl
5 None
