In nlmixr2est: Nonlinear Mixed Effects Models in Population PK/PD, Estimation Routines

Preprocessing hook: mu-expand non-mu structural fixed-effect thetas for the nonparametric engines, before the rest of the pipeline builds on the ui. Doing it here (rather than mutating the ui mid-setup) keeps the injected pseudo-etas consistent through covariate/mu processing and model compilation. Off when control$muExpand is FALSE.

Description

Preprocessing hook: mu-expand non-mu structural fixed-effect thetas for the nonparametric engines, before the rest of the pipeline builds on the ui. Doing it here (rather than mutating the ui mid-setup) keeps the injected pseudo-etas consistent through covariate/mu processing and model compilation. Off when control$muExpand is FALSE.

Usage

.nlmixr0preProcessNpMuExpand(ui, est, data, control)

Arguments

ui	rxode2 ui
est	estimation method (all methods are shown by 'nlmixr2AllEst()'). Methods can be added for other tools
data	nlmixr data
control	The estimation control object. These are expected to be different for each type of estimation method

Value

list(ui=) when the model was expanded, else NULL
