Web1. Model evaluation is an important issue in population analyses. Our aim was to perform and illustrate metrics and techniques for internal and external evaluation with an application to population pharmacokinetics of hydrochlorothiazide (HCTZ). 2. A nonlinear mixed effects model was used to study the pharmacokinetics of HCTZ. WebNov 26, 2014 · 19. Population pharmacokinetic (PK) modeling involves estimating an unknown population distribution based on data from a collection of nonlinear models. A drug is given to a population of subjects. In each subject, the drug’s behavior is stochastically described by an unknown subject-specific parameter vector ∂.
