Hello Friends,
Could anyone help me debug this message in the beginning of a NONMEM report file?
========================================================
.........
0ERROR SUBROUTINE CALLED WITH EVERY EVENT RECORD.
1
MONITORING OF SEARCH:
0PROGRAM TERMINATED BY OBJ
ERROR IN ELS WITH INDIVIDUAL 1127 ID=0.00000000E+00
VAR-COV OF DATA FROM INDIVIDUAL RECORD ESTIMATED TO BE SINGULAR
MESSAGE ISSUED FROM ESTIMATION STEP
AT INITIAL OBJ. FUNCTION EVALUATION
========================================================================
The individual 1127 is the last one in the data file and I have no idea how this ID=0000
came from. I checked my data file, which was created via SAS 8.2, but nothing useful was
found. I used the same SAS program to generate many different data files only 2 out
of 8 files had this problem.
Thanks,
Alan
