Dear users:
Could anyone suggest me some possible reasons for the following error to occur?

With the exact same model and data, I got very good estimates (see below) for all the
parameters and SEs if FO is used. Once I switched to FOCE with interaction, this error
will show up and stop the fitting. Even after I put IF (ABS(ETA(1)).GT.10) EXIT 1 100
IF (ABS(ETA(2)).GT.10) EXIT 1 200
IF (ABS(ETA(3)).GT.10) EXIT 1 300
IF (ABS(ETA(4)).GT.10) EXIT 1 400
in my $PK block, the error messages still persist.

Hello Yaning
You may want to check the lower bounds of the thetas and use exit statements
for CL and V.
