ThreeComp_Coefficient_Exponent: Convert pharmacokinetic parameters for three compartment...

In PKconverter: The Parameter Converter of the Pharmacokinetic Models

Description

Calculate pharmacokinetic parameters with parameters (A, B, C, alpha, beta, and gamma) in two compartment model "Aexp(-alpha)+Bexp(-beta)+Cexp(-gamma)"

Usage

ThreeComp_Coefficient_Exponent(A,B,C,alpha,beta,gamma,A.sd=NA,
   B.sd=NA,C.sd=NA,alpha.sd=NA,beta.sd=NA,gamma.sd=NA,
   covar=c(AB=NA,AC=NA,Aalpha=NA,Abeta=NA,Agamma=NA,BC=NA,Balpha=NA,
   Bbeta=NA,Bgamma=NA,Calpha=NA,Cbeta=NA,Cgamma=NA,alphabeta=NA,
   alphagamma=NA,betagamma=NA),...)

Arguments

A	parameter in one compartment model "Aexp(-alpha)"
B	parameter in two compartment model "Aexp(-alpha)+Bexp(-beta)"
C	parameter in three compartment model "Aexp(-alpha)+Bexp(-beta)+Cexp(-gamma)"
alpha	parameter in one compartment model "Aexp(-alpha)"
beta	parameter in two compartment model "Aexp(-alpha)+Bexp(-beta)"
gamma	parameter in three compartment model "Aexp(-alpha)+Bexp(-beta)+Cexp(-gamma)"
A.sd	standard error of A
B.sd	standard error of B
C.sd	standard error of C
alpha.sd	standard error of alpha
beta.sd	standard error of beta
gamma.sd	standard error of gamma
covar	covariances among parameters
...	arguments to be passed to methods
