Dear All:
Suppose I have the 2 following data set1:
Data 1
id v
1 4
1 2
2 6
2 7
-------------
Data 2:
id x y z
1 4 a 7
1 4 b 8
1 4 c 9
2 6 a 7
2 6 b 8
2 6 c 9
Note that _x_ is a fixed effect in data 2 as well as the combined data
set. Given that, do you know how I can append data 1 to data 2 so
that the combined data set will have infor from both data 1 and 2 and
some missing values due to mismatch between v and (y,z). Specifically,
the combined data for the first observation looks like the following:
Combined data:
id x y z v
1 4 a 7 mis
1 4 b 8 mis
1 4 c 9 mis
1 4 mis mis 4
1 4 mis mis 2
......
Many thanks!
