Dear Martin and Elodie and others, Thanks for pointing out this nice function of PsN-- I think I will give it a try this time.

The Bootstrap functionality is primarily used for obtaining parameter uncertainties. A detailed userguide for the SSE functionality is presented at the PsN webpage (see link below). http://psn.sourceforge.net/PDF_docs/sse_userguide.pdf Write to the PsN mailing list if you experience any troubles and need help (psn-gene...@lists.sourceforge.net).

With PSN installed you would simply do: bootstrap final_model.mod -samples=200 PSN would take care of unsuccessful runs and provide a nice summary of the individual estimates.

Is there anyway nonmem could continue go on? Or, does someone know alternative way to achieve the goal? thanks
