Error message 72

From: Jiun-Li Jang <jjang@voicenet.com> Subject: Error message 72 Date: Tue, 31 Jul 2001 22:59:29 -0400 Dear all, I am a new NM user, I started my first NM study recently and encountered a problem (floating error-overflow; Error message 72). I need your help to direct me how to resolve this problem. I have tried to change omega and sigma values, comma out the ALAG1 and ETA3. I have also tried to change the boundary conditions (enlarged or decreased). The error message was always shown, then the program was stopped. Very few times I could get the table in the directory but not output file if I was not kicked out in the begining. I realized that the number of subjects may not be enough to conduct population PK analysis, it was just a try, if the model works, then I'll add more subjects. Please find the attached control file and data file, I thank you in advance for taking your time and effort to teach me. J.J.
