Hi,
Does anybody know how to form synthetic panels from
repeated cross-sections? It appears I have
successfully constructed the 'pseudo panel' but there
are a few things I don't understand about the cohort
means for example pstatus and loc2. pstatus is meant
to be a categorical variable 0, 1 and 2. Now if you
take cohort means of pstatus you get something like
this
+---------------------------------------+
| cohortid yr loc2 pstatus |
|---------------------------------------|
1. | 1 1 1.6363636 1.4545455 |
2. | 1 2 1.9230769 1.6923077 |
3. | 2 1 1.9090909 1.4090909 |
4. | 2 2 1.7 1.7 |
5. | 3 1 1.7179487 .94871795 |
|---------------------------------------|
6. | 3 2 1.6363636 1.6818181 |
7. | 4 1 1.7692307 1.1538461 |
8. | 4 2 1.9285715 1.3571428 |
9. | 5 1 1.8235294 1.0784314 |
10. | 5 2 1.7945205 1.6027397 |
How do I explain the fact that the pstatus of cohort 3
in yr 1 was 0.95 and all the rest which fall between
pstatus 1 and 2 ( eg. 1.45). The same is for loc2
which is supposed to be 1 for urban and 2 for rural.
Now I get something like 1.63 for cohort 1 in yr 1.
Any help will be much appreciated.
