Subject: ENTIRE RECORD IS BLANK & prediction values are zero

Dear nmusers:
I had some steady state data and I tried to run a nonlinear MM model (ADVAN10). My data set is listed as below:
ID EVID TIME AMT SS II DV MDV
1 4 0 100 1 8 0 1
1 0 3 0 0 0 14 0
1 4 0 200 1 12 0 1
1 0 3 0 0 0 10 0
2 4 0 150 1 12 0 1
2 0 3 0 0 0 14 0
3 4 0 400 1 24 0 1
3 0 3 0 0 0 12 0
3 4 0 200 1 24 0 1
3 0 3 0 0 0 27 0
3 4 0 450 1 24 0 1
3 0 3 0 0 0 17 0
.......
I tried to check my data set by running CHECKOUT. However, after running, I got the following messages:
(DATA WARNING 6)
ENTIRE RECORD IS BLANK
When I got in the output file, in the "TABLES OF DATA AND PREDICTION", all the prediction values are zero.
Could someone kindly tell what dose that mean?
Thanks in advance
Clement

Clement,
"ENTIRE RECORD IS BLANK" suggests you have a blank line in your file, probably at the end of the file.
Predictions all zero is normal behavior for $DATA CHECKOUT (it just checks out data :). If you want predictions without estimation, use $EST MAXEVAL=0 or $SIM.

Dear Nmusers,
The following is the Control and Data files that I tried to run ADVAN10. However, it kept showing "NUMERICAL DIFFICULTIES WITH STEADY STATE SOLUTION. MESSAGE TERMINATED BY OBJ". Could someone tell me what does that mean?
Your help is much appreciated
