Research of quantities medicine diagnose model based on fuzzy cluster analysis and stepwise discriminatory analysis
Miao Zhang · Medical Information · 2005
Fuzzy cluster analysis,with the combination of fuzzy moths and statist ical analysis are widely used in the quantities medicine diagnose.This article i ntroduces the related elementary contents of Fuzzy moths method and statistical analysis.Based on it, we developed a model. According to the analysis of 148 cas es of stomach cancer and the others stomach diseases, which are collected by the digesting department of Xenon Hospital. According to the rules of Fuzzy Cluster Analysis, we found discriminate function by using the stepwise discriminatory a nalysis program, then used it to predict and diagnosis the diseases of stomach p atients. It produces appropriate diagnosis about 96.8% in the retrospective test of the 100 cases we collected. In the following practical use, it produces appr opriate diagnosis about 91.7%,based on the above work,we develop a computer aide d medical differential diagnosis system. The system is designed in VB program l anguage, the whole process is finished in the computer, the interface is friendl y and confinement, and all these demonstrate this system is effective and practi cal.
