I have the following problem:
I have data on individuals indexed by a unique identifier, SERNO. In
addition to SERNO, I have a vector of variables Z which are measurements
taken on each individual at time t. Lastly, I have a variable SERNO2 which,
for each case, gives the value of SERNO for a matched case in the data set.
What I wish to do is create a second vector of variables, X, which copy the
values of Z for the case indexed by SERNO2 to each value of SERNO. Any
suggestions?
