The mathematic model for target positioning in the case of detecting through the wall body is derived firstly in the paper. Due to the refraction interference by the wall body, the derived equations are the transcendental equation, which can be solved by the numerical calculation method. Newton method is used to solve the nonlinear equations and the simulation result is obtained in single-transmitter...
The linear structural equation model is introduced in this paper. And as an example of the linear structural equation model, a new customer satisfaction indices model is built, Sas procedure for parameter estimation is given, and the model is fitted by using sampling data and the results are evaluated.
