Re: [NMusers] Why should we avoid using micro rate constants?

are treating amount and concentration as same unit. Hence, it should be avoided. You can still fit model with micro-constant but requires defining volume and conversion of amount into concentration to do proper modeling, Regards, SaeHeum Song, Independent Consultant, On Tue, Feb 5, 2019 at 2

Pls check what you have compared. You have used sigma 1 for nonmem not for mrgsolve. Even if you use sigma q for Mrgsolve, the results will be slightly different due to fittong vs. Simulation via random numbers. Hope it helps On Tue, Feb 11, 2020, 10:43 AM Le Louedec Felicien <

Dear Patricia, Your infusion time will not be semantically distributed. I suppose maximum distribution toward planned DUR. But you may have left half of the distribution curve with maximum value of predetermined infusion time. So model is likely to be D1* (1-abs(THETA(1)*EPA(1))) On Wed,

Upon my review, A(4) is defined as GR and Kill rate. Without initial value of A(4), A(4) will remain 0. Also you defined GR for control only and control groups were ignored. There will be no growth rate defined for all other groups. For A(5) CLPAR was given by amount of A(4) but corresponding
