Hello Ada,
I could not reproduce your problem with a random data. It seems to be
working as it is supposed to:
. list
+--------------------+
| income2 income~d |
|--------------------|
1. | 1 0 |
2. | 2 0 |
3. | 3 0 |
4. | 4 0 |
5. | 5 0 |
|--------------------|
6. | 6 1 |
7. | 7 1 |
8. | 8 1 |
9. | 9 1 |
+--------------------+
. tab1 income2 income2_d
-> tabulation of income2
income2 | Freq. Percent Cum.
------------+-----------------------------------
1 | 1 11.11 11.11
2 | 1 11.11 22.22
3 | 1 11.11 33.33
4 | 1 11.11 44.44
5 | 1 11.11 55.56
6 | 1 11.11 66.67
7 | 1 11.11 77.78
8 | 1 11.11 88.89
9 | 1 11.11 100.00
------------+-----------------------------------
Total | 9 100.00
-> tabulation of income2_d
income2_d | Freq. Percent Cum.
------------+-----------------------------------
0 | 5 55.56 55.56
1 | 4 44.44 100.00
------------+-----------------------------------
Total | 9 100.00
------------------------------------------------------------------------------------------------------------
The situation that you describe (Stata confusing variables) might be a
result of an str0 bug that I posted here some time ago. It might also
be a result of an improper data conversion using external programs.
It would help if:
1. you specify your Stata version (number, platform etc)
2. you tell us if any other programs were involved into data
processing (e.g. the file is a product of StatTransfer, DBMS Copy,
etc)
3. you try other Stata commands and tell us if the problem relates to
tab1 only, or to other commands as well (e.g. try -regress income2
income2_d-)
4. Do you see your data correctly after -list-, or in the data editor?
Best regards,
Sergiy Radyakin
