Numerical continuation method for nonlinear curve fitting by use of least square method
2003
It is necessary to solve a system of nonlinear equations for fitting the curve of nonlinear function by use of the least square method. Based on the global convergence method for solving the nonlinear equations, the numerical continuation method is adopted to study the least square fitting of nonlinear functions, and the sufficient condition is also given for the numerical method to realize the global convergence.
