I am seeking to simulate AUC-response relationships using $PRED, but
without $PK, since there are no TIME points involved. After generating the
simulated AUC-response (AUC, Effect) data, I would then evaluate them in
one of two effect data analysis models.
Several issues are confusing me:
1. In the SIMULATION 2 EXAMPLE, the generated table is described as having
the "concatenated output of all the subproblems...". what does this mean,
since I usually consider concatenation in FORTRAN to be a merging of
strings? Are the DV or other simulated values in the TABLE some form of
aggregate of the 10 repetitions? If not, where did the DVs from the
2. What are the advantages of using SUBPROBLEMS=x as opposed to providing
dummy "patient" IDs of 1..X?
Thanks very much.

Concatenated literally means chained together. With NONMEM this means:
results of subproblem 1
results of subproblem 2
Advantage of using SUBPROBLEM is that you can easily select the number of replications without having to change the original data file template.
Bottom line, just try it and look at the TABLE output...
