Hello Pumas team; I guess I have a problem with the simulation. Most of the code is taken from the tutorial part, some additional parameters added. I have the issue as: MethodError: objects of type NamedTuple{(:Ka, :K2,…

Hi everybody, I am working on population pharmacokinetic and estimated already V\_pop and Cl\_pop with one compartments model. I am willing to know, how can we go for PTA analysis using Pumas. Thank You. Mohammad

Hi guys, Just learning to simulate with Julia codes and build model libraries. I have written a Non linear model for Phenytoin, Can someone verify if this is modeled correctly? A doubt I have is with entering Vmax values…

I would like to simulate a population, by only changing the parameters of the model not a covariate like Wt, but every parameter- When I do pop = Population(map(i -\> Subject(id=i,evs=regimen),1:10)) obs = simobs(model,…
