1THE 'HYBRID' TECHNIQUE FOR RISK ANALYSIS OF SOME DISEASES显示文摘Based on the data obtained from a survey recently made in Shanghai, this paper presents the hybrid technique for risk analysis and evaluation of some diseases. After determination of main risk factors of these diseases by analysis of variance, the authors introduce a new concept ’Illness Fuzzy Set’ and use fuzzy comprehensive evaluation to evaluate the risk of suffering from a disease for residents. Optimal technique is used to determine the weights wi in fuzzy comprehensive evaluation, and a new method ’Improved Information Distribution’ is also introduced for the treatment of small sample problem. It is shown that the results obtained by using the hybrid technique are better than by using single fuzzy technique or single statistical method.SHANGHANJI LUYUCHU XUXUEMEI CHENQIAN 2001Chinese Annals of Mathematics,Series B2001,22,4:2
2NON-PARAMETRIC LEAST SQUARE ESTIMATION OF DISTRIBUTION FUNCTION显示文摘By using the non parametric least square method, the strong consistent estimations of distribution function and failure function are established,where the distribution function F(x) after logist transformation is assumed to be approximated by a polynomial.The performance of simulation shows that the estimations are highly satisfactory.ChaiGenxiang HuaHong ShangHanji 2002Applied Mathematics(A Journal of Chinese Universities)2002,17,4:1
