| Abstract: | On the basis of the concerning nonlinear curvature measures of strength of the model of adjustment, the nonlinear curvature measures of strength for the model of adjustment of free networks with general rank deficiency is put forward in this paper. The acceptance of linearized approximation for nonlinear adjustment model of free networks with general rank deficiency is validly solved by the means of the method presented in this paper. And it is of great importance to analyze the confidence fields of parameters and statistical quality of estimator to nonlinear least squares for nonlinear adjustment of free networks with general rank deficiency. |
