I’m trying to fit a global PK model to data from more dose levels from different subjects. I.e. the aim is to fit a single set of parameters that can cover all dose levels. All plasma concentration time profiles are from 0-16h. I can’t figure out how to map the main sheet and dosing sheet to allow for a global/integrated fit. When sorting on dose I get individual sets of parameters from each dose level in the output so not sure how to organize the data. Input appriciated.
