Sample NLME parameters from their uncertainty distribution

Sample NLME parameters from their uncertainty distribution

sampleParamFromUncertainty(
  spec,
  Npop = if (is_IQRnlmeParamSpec(spec)) spec$Npop else 1L
)

Arguments

spec

a filename (character string) denoting the path to a GPF excel file, or a GPF object, or an IQRnlmeParamSpec object.

Npop

integer denoting the number of populations to sample. Default: if(is_IQRnlmeParamSpec(obj)) obj$Npop else if(FLAG_SAMPLE==2) Nsamples else 1L.

Value

a data.frame of Npop rows with columns ID.POP and parameter value columns as follows:

X,Y...:

reference population values for model parameters X,Y...

omega(X),omega(Y)...:

IIV population values for model parameters X,Y,...

corr(X,Y),...:

IIV correlation population values for model parameter pairs.

beta_X(COVRT1),beta_Y(COVRT2),...:

Covariate coefficient population values.

error_PROP1,...:

Residual error population parameters.
