Dear all,
A simplified version of my data looks as follows:
ID Group X
1 a 5
2 a 7
3 a 9
4 a 8
5 b 3
6 b 4
7 b 9
..........................
I would like to generate a new variable whose value is the 75 percentile of
other individuals in the same group as the concerned individual. For
example, for the first individual (ID=1), this will be: 75 percentile
of {7, 9, 8}.
I would highly appreciate if someone could suggest me a solution for this.
Thanks and Have A Great Day!
Sincerely yours,
Quang
