Hi,
I have panel data and I want to replace observations of one group with the same variable's observations for another group. I have 31 organizations in my dataset and I would like to use observations of UN for the variables of disaster and damage for other UN agencies as well (UN agencies have "1" under the UN_system dummy variable). I'm very much open to suggestions on this! Thank you.


Organization---Year----disasters----damage---UN_system
UN----------------1990-------1-------------2-------------1
UN----------------1991-------4------------ 3-------------1
UNHCR----------1990-------.------------. ------------ 1
UNHCR----------1991-------.------------. ------------ 1
UNICEF----------1990-------.------------. ------------ 1
