Chiung-Ya Tang--
You should not send rich formatting to Statalist--the FAQ advises that
this is a text-only list--and it is easy to choose not to in gmail.
As for your question, see -help _variables- for use of _n e.g.
clear
input gp id v1
1 1 3.2
1 2 4.5
2 1 3.1
2 2 3.3
3 1 .
3 2 2.3
end
bys gp (id): g v2=v1[3-_n]
l, noo clean

I am learning STATA and would like to use it to analyze a set of dyadic dat=
a. The data is as following:
Group member V1
=E3=80=801 1 3.2
=E3=80=801 2 4.5
=E3=80=802 1 3.1
=E3=80=802 2 3.3
I wish to generate a new variable--V2 in which responses from V1 are exchan=
ged within a group. So, it should look like this:
Group member V1 V2
=E3=80=801 1 3.2 4.5
=E3=80=801 2 4.5 3.2
=E3=80=802 1 3.1 3.3
=E3=80=802 2 3.3 3.1
