Hi Norman, If you have the most recent PsN version, then there is functionality to simulate with uncertainty in population parameters. PsN can use either the nonmem cov matrix or (non-parametric) bootstrap for that purpose. Each replicate dataset that is simulated would be simulated with a different set of population parameters. Unless you want to do a sensitivity analysis on parameters that you have fixed in your analysis, I think this is exactly what you need. Best regards Jakob Sent from my iPhone
