Journal ArticleDOI
Computing normalised prediction distribution errors to evaluate nonlinear mixed-effect models: The npde add-on package for R
Emmanuelle Comets,Karl Brendel +1 more
TL;DR: An add-on package for the open source statistical package R, designed to compute normalised prediction distribution errors (npde), which takes into account the full predictive distribution of each individual observation and handle multiple observations within subjects.
Journal ArticleDOI
Metrics for External Model Evaluation with an Application to the Population Pharmacokinetics of Gliclazide
TL;DR: Normalized prediction errors calculated without any approximation, and metrics based on hyperparameters or on objective function have good theoretical properties to be used for external model evaluation and showed satisfactory behaviour in the simulation study.
Journal ArticleDOI
Overview of model-building strategies in population PK/PD analyses: 2002-2004 literature survey.
Céline Dartois,Karl Brendel,Emmanuelle Comets,Céline M. Laffont,Christian Laveille,Brigitte Tranchand,F. Mentré,A Lemenuel-Diot,Pascal Girard +8 more
TL;DR: This survey of published population pharmacokinetic and/or pharmacodynamic analyses from 2002 to 2004 was conducted and an evaluation made of how model building was performed and reported, revealing deficiencies in reporting information on model building.
Journal ArticleDOI
Evaluation of different tests based on observations for external model evaluation of population analyses
TL;DR: NPDE represent a better approach than NPC, since in order to perform tests on NPC, a decorrelation step must be applied before, and NPDE is also a good tool to evaluate model with or without covariates.
Model evaluation in nonlinear mixed effect models, with applications to pharmacokinetics
Emmanuelle Comets,Karl Brendel +1 more
TL;DR: In this article, the authors illustrate the use of some recently proposed metrics on several simulated datasets, including Visual Predictive Checks (VPC), prediction discrepancies (pd), and normalised prediction distribution errors (NPde).
