Hi,
I have a somewhat complex setup for powder dissolution testing that I would like to model in Phoenix. The issue is that I would like to be able to fit parameters on multiple levels in the model:
-Some parameters I would like to fit per individual test
-Some parameters I would like to fit per formulation (but keep constant between replicates of the same formulation)
-Some parameters I would like to fit as a single parameter for all tests (across formulations and replicates)
Could this be achieved in WinNonlin?
