A Note on Foss's Method of Obtaining Initial Estimates for Exponential Curve Fitting by Numerical Integration

Abstract

Although much is written on the estimation of parameters in nonlinear models, very little attention is given to the problem of finding the initial parameter estimates needed to commence an iterative estimation procedure. A good choice of initial estimates ensures that the iterative scheme converges quickly and, hopefully, to the correct point. In this communication we consider methods for obtaining initial parameter estimates for the polyexponential function
