应用判别分析方法筛检高危险人群的探讨

A Approach to IdentifyHigh Risk Population by Stepwise Discriminary Analysis

本文采用逐步判别分析方法,探讨了应用病例-对照研究数据和结果建立判别用数学模型的方法,以期筛检高危险人群。结果表明,采用数学模型筛检高危险人群的办法对于开支大的群体研究课题具有显著的经济效益,而且由于样本的适度变小,有利于进行质量控制和观察管理。本方法在低发病率疾病的预防措施研究领域里具有较大的实用性和经济效益。

Based on the data of a case-control study onbreast cancer,a set of discriminary functions wereestablished for identifying high risk population.Theaim of this work was to explore the possibilityto decrease the sample size for minimizing the costand better quarlity control in Prospective researchor So for purpose of decreasing the cost and betterquarlity control in a prospective research or conve-ntion trial,a high risk population identified by st-epwise discriminary analysis was suggested to beused.
