The Method of Least Squares Curve Fitting

The method of least squares curve fitting is used proverbially for the test data processing, etc. It is inequitable to process physical parameters by some usual methods of curve fitting. Those methods are performed only by minimizing the fitting error of one physical parameter, but do not take other parameters into account. The method of least squares curve fitting processes each physical parameter equally. The simulation also proves that this method of least squares curve fitting method is right and effective.
