| The purpose of this paper was to introduce the approach of multiple Logistic regression analysis for the binary data collected from the m∶n paired design. Firstly, the basic concepts that need to be understood were introduced. Secondly, the basic principle of constructing such regression model was presented. Finally, the whole process of computing with SAS was shown by an example. In this process, the following four useful enlightenments had been obtained: ① it was necessary to ensure that the scientific research data obtained were worth analyzing; ② it was necessary to generate the derived variables based on quantitative independent variables; ③ it was necessary to adopt the “stepwise method”“forward method” and “backward method” to screen the independent variables at the same time; ④ it was necessary to use several approaches to evaluate the goodness of fit of the different regression models. |
