scatterplot matrix. I have two stata data files. The first contains the
raw data from an experiment. The second file contains calculated predicted
values which I would like to plot as a line on top of the observed values in
the first file.
Various permutations of the -merge- command have failed to merge the two
files.
I've made plots of each using:
graph response resistnc, by(idnum) total jitter(2) ylabel(0, 2 to 10)
and
graph R resistnc, by(idnum) connect(l) ylabel(0, 2 to 10) total
Suggestions?
Details follow..
Each subject given 6 stimuli, response to each stimulus measured five
times. Thus the file looks like:
list idnum resistnc response
idnum resistnc response
1. 401 0 0
2. 401 0 0
3. 401 0 0
4. 401 0 .7
5. 401 0 0
6. 401 2.5 1.9
7. 401 2.5 1.5
...
The second file contains a predicted response (R) based on a predicted curve
for each subject.
. list idnum resistnc R
idnum resistnc R
1. 401 0 .14
2. 401 2.5 2.489528
3. 401 5 3.538459
4. 401 10 5.055678
5. 401 20 7.25025
6. 401 30 8.963791
7. 402 0 .4
8. 402 2.5 1.289712
9. 402 5 2.060106
10. 402 10 3.497576
11. 402 20 6.179739
