Biexponential fitting for noisy data with error propagation

Biexponential time‐series models commonly find use in biophysics, biochemistry and pharmacokinetics. Indeed, reactions that are described by biexponential functions are typical for many biological processes. The kinetics of these reactions are modelled by transcendental irrational equations interconnecting the reagent concentrations, time and rate constants. The biexponential is apparently a case of nonlinear regression, and as such, very often...
