| Summary: | This paper shows an analysis of the order for the approximation and roundoff
errors in combined numerical scheme with recorrector strategy of Adams–Moulton–
Bashfort family. These methods are used for the numerical solution of the estimation
problem in models defined by dynamical ODE. Our interest is avail oneself of “family
or kind” of methods which will be efficient or at least competitive for the numerical
solutions of this type of problems. This strategy is consistent with the present tendency in the use of models with minimal square objective function for the adjustment via
optimization algorithms with and without constrained and explicit, semi-explicit or
implicit numerical methods.
Keywords: Recorrector strategy numerical methods, multi-step, stiffness, roundoff errors.
