Re: [NMusers] FO vs FOCE, sequential vs simultaneous

Hi Alan, Here: http://quantpharm.com/pdf_files/PAGE_2008_Poster_1268_web.pdf I used all datasets that I had, and I was not able to find any problem where FO was superior to FOCE. Not-converged FOCE is better, in my opinion, than converged FO (although you can always check using diagnostic

There's an additional, related point to consider with respect to estimation method, in selecting a simultaneous vs sequential approach In the case where simultaneous modeling under conditional estimation is not feasible (run-time, convergence, etc), it is preferable to use a

Leonid, Thanks very much for this experimental data support confirming again the wisdom of using FOCE rather than FO and not worrying about convergence. Nick Leonid Gibiansky wrote: Hi Alan, Here: http://quantpharm.com/pdf_files/PAGE_2008_Poster_1268_web.pdf I used all datasets that I
