VPC simulation
Usage
vpcSim(
object,
...,
keep = NULL,
n = 300,
pred = FALSE,
seed = 1009,
nretry = 50,
normRelated = TRUE
)Arguments
- object
This is the nlmixr2 fit object
- ...
Additional arguments passed to
nlmixr2est::vpcSim().- keep
Keep character vector
- n
Number of simulations
- pred
Should predictions be added to the simulation
- seed
Seed to set for the VPC simulation
- nretry
Number of times to retry the simulation if there is NA values in the simulation
- normRelated
should the VPC style simulation be for normal related variables only
Examples
# \donttest{
one.cmt <- function() {
ini({
## You may label each parameter with a comment
tka <- 0.45 # Log Ka
tcl <- log(c(0, 2.7, 100)) # Log Cl
## This works with interactive models
## You may also label the preceding line with label("label text")
tv <- 3.45; label("log V")
## the label("Label name") works with all models
eta.ka ~ 0.6
eta.cl ~ 0.3
eta.v ~ 0.1
add.sd <- 0.7
})
model({
ka <- exp(tka + eta.ka)
cl <- exp(tcl + eta.cl)
v <- exp(tv + eta.v)
linCmt() ~ add(add.sd)
})
}
fit <- nlmixr(one.cmt, theo_sd, est="focei")
