Thank you Martin.
I was trying out the Statsby command using the following dummy dataset. I
am using version 8 of STATA.
+------------------------------+
| cid score iq nutrit~n |
|------------------------------|
1. | C1 100 210 200 |
2. | C1 90 190 180 |
3. | C2 88 186 150 |
4. | C2 80 200 210 |
5. | C3 99 180 199 |
|------------------------------|
6. | C3 90 188 211 |
7. | C1 30 190 201 |
8. | C1 80 180 190 |
9. | C2 60 155 176 |
10. | C2 50 145 145 |
|------------------------------|
11. | C3 70 198 134 |
12. | C3 90 188 122 |
+------------------------------+
I saved the above in a file.
Then I gave the command
statsby "regress score iq nutrition " _b, by(cid)
I get this
command: regress score iq nutrition
statistics: b_iq = _b[iq]
b_nutrit~n = _b[nutrition]
b_cons = _b[_cons]
by: cid
The data editor has 4 columns now: cid, b_iq, b_nutrit~n and b_cons but
the cells are all empty! Any idea where I am going wrong?
