| Abstract: | Objective To explore the diagnosis and treatment of multivariable multicollinearity in the logistic regression analysis. Methods The data with multivariable multicollinearity were diagnosed and treated using the logistic regression model method improved by principal component analysis. Results The effect of multicollinearity among variables were eliminated in the regression model and an ideal mathematical model was constructed. Conclusion The new method is effective and feasible for diagnosis and treatment of multivariable multicollinearity in the logistic regression model analysis. |
