Hi,
I have a panel data and using XTTRANS command I get a
matrix as follows:
| stat
stat | 0 1 2
3 | Total
-----------+--------------------------------------------+----------
0 | 843 1,989 139
126 | 3,097
| 27.22 64.22 4.49
4.07 | 100.00
-----------+--------------------------------------------+----------
1 | 1,294 13,259 1,987
867 | 17,407
| 7.43 76.17 11.41
4.98 | 100.00
-----------+--------------------------------------------+----------
2 | 99 1,547 1,271
834 | 3,751
| 2.64 41.24 33.88
22.23 | 100.00
-----------+--------------------------------------------+----------
3 | 127 837 693
2,155 | 3,812
| 3.33 21.96 18.18
56.53 | 100.00
-----------+--------------------------------------------+----------
Total | 2,363 17,632 4,090
3,982 | 28,067
| 8.42 62.82 14.57
14.19 | 100.00
First of all, the total number of observations here,
28067 is not the same as (fewer than) the number of
observations for the sample if I do .sum. Also, if I
do:
. tab stat if lag==0;
stat | Freq. Percent Cum.
------------+-----------------------------------
0 | 946 27.59 27.59
1 | 2,174 63.40 90.99
2 | 166 4.84 95.83
3 | 143 4.17 100.00
------------+-----------------------------------
Total | 3,429 100.00
The number of observations don't equal to the
corresponding ones in the first row of the matrix
either.
I really appreciate it if anyone could kindly give me
some information or tips as to what I am missing here.
Each person has only one spell of observations on STAT
in the sample, though the numbers of observations per
spell diff.
Thank you so much in advance,
Carol
