TwoComp_Volume_Exponent: Convert pharmacokinetic parameters for two compartment model

Description

Calculate pharmacokinetic parameters with volume of distribution(V1), transfer rate constant (k12), and parameters (alpha and beta) in the model "Aexp(-alpha)+Bexp(-beta)"

Usage

TwoComp_Volume_Exponent(V1,alpha,beta,k21,V1.sd=NA,
 alpha.sd=NA,beta.sd=NA,k21.sd=NA,
 covar=c(V1alpha=NA,V1beta=NA,V1k21=NA,alphabeta=NA,
 alphak21=NA,betak21=NA),...)

Arguments

V1

The volume of distribution of compartment 1

alpha

parameter in one compartment model "Aexp(-alpha)"

beta

parameter in two compartment model "Aexp(-alpha)+Bexp(-beta)"

k21

transfer rate constants from compartment 2 to compartment 1

V1.sd

standard error of V1

alpha.sd

standard error of alpha

beta.sd

standard error of beta

k21.sd

standard error of k21

covar

covariances among parameters

...

arguments to be passed to methods
