These indexes could be complementary tools to the existing statistical and graphical techniques for population pharmacokinetic data analysis. Applied to explore observational data, the information indexes were used on the individual empirical Bayes estimates obtained in one-stage data analysis by the nonlinear mixed effect model. The rationale for using these indexes is shown using validation data for a drug under development.
