The Theory and Application of Generalized Logistic Regression for Risk Analysis of Fuzzy States(4)——Generalized Unconditional and Conditional Logistic Regression Models

A general risk function is suggested and applied to logistic regression models in this paper.Through conditional component analysis and application to study data of liver cancer,a concept about nonlinear amplification action,ariginating from the crossing effects of weakly correlative2influencing factors,is proposed and the importance viewing things in their total is emphasized for preventive medicine studies.
