Abstract:

The paper presents and documents a FORTRAN subroutine for applying Goodmans method to any given system of ordinary differential equations. The method determines those values of the parameters and initial conditions of the system that best fit the solution curves to observed data. No a priori knowledge or assumptions regarding the form of the solution are required.
