Dear List
I have an unbalanced data and I want to transform it into
cross-sectional data, because the drop out rate is high and I am
interested in the cross-sectional comparison. This data includes 3
waves, and new observations were added each year to maintain a
reasonable sample size. Some individual were measured once out of the
3 waves, some twice and some three times. An simple example of the
data is pasted below.
person year income age sex
1 2003 1500 27 1
1 2004 1700 28 1
2 2003 2100 41 2
2 2004 2100 42 2
2 2005 2200 43 2
3 2004 3000 35 1
Any comment or suggestion is appreciated! Thank you very much for your
consideration!
