I got NONMEM result without standard error of estimate. It showed 'covariance step aborted' message.. could you please let me know how can I get standard error of estimate? 2. I set upper bound as 8, and final estimate comes "8!". In this case, do I have to delete upper bound and set unlimited?? 3. With another data, after 40 iteration, NONMEM is still running but stuck with this. What I have to do with this?.. NUMSIGDIG: 2.4 2.9 2.8 2.7 .......... Thanks a lot!!
