JANA: a new iterative polyexponential curve stripping program

A new iterative polyexponential curve stripping technique for the provision of initial pharmacokinetic parameter estimates has been developed. Such estimates are required for nonlinear least-squares curve fitting. In contrast to conventional curve stripping, this new technique does not make any assumption about the relative magnitudes of the exponential rate constants. Hence, the parameter estimates which it provides are free of the bias which may arise in conventional curve stripping. A BASIC program called JANA has been developed to implement the new curve stripping procedure.
