【Abstract】 The parameter evaluating method—Jacobian matrix recursion method for solving non linearization regression model is discussed and applied to the study of tobacco. Meanwhile, this method is compared with the conventional one. The results show that the Jacobian matrix recursion method is obviously superior to the later one, exspecially for the residual square sum (The maximum decrease ratio is up to 68.4%).更多还原
