Dears,

 

I was testing out the following code, presented by Tom at a meeting a
while back, for independent estimation of individual PK data.

 

The code works just fine with Single dose data, even when there are
multiple periods, but it fails to analyze the true "multiple dose" data.
For the single dose cross-over studies, I have used both EVID=1 or
EVID=4 for the second and all subsequent doses...and both approaches
work fine. However, when I try to analyze multiple-dose data, the code
does not work anymore.  It analyzes the first subject but fails to pick
up the second subject etc... 

 

I was wondering whether it is possible to use similar method to analyze
multiple dose data!  BTW, I am running this on NM7, but it also works
fine under NM6.

 

I have attached the Model file below and excerpts from the output of
failed run is also attached...

 

Thanks for your suggestions in advance.

Note: After the first record of ID=602, the other records are all zeros.
 
Also, I see the following for the ID=602 (second subject in the data
set): Clearly there is no data in the field to be analyzed, which
results in this outcome:
