基于11种灰色关联度法的卫生指标序列应用比较分析

Demonstration and Comparison Study to Equidistance Sequence Analysis in Health Field Based on 11 Kinds of Grey Relational Degree Methods

以序列灰色关联分析方法应用为视角,简述多种关联度方法基本流程;借助算例验证分析,为类似问题研究提供技术参考.分别阐述11种灰色关联度法原理及步骤,以医疗卫生指标时间序列为例计算实现.简要给出所有方法实施步骤,方法原理及信息利用有差异.序列间关联度结果与实际问题演示情形一致.11种灰色关联度法有集成讨论意义,有待于卫生领域综合对比及科学选用,也可以为因素筛选、综合评价、时序分析和聚类优化等应用问题提供借鉴.

Method application of sequence grey correlation analysis as angle of view,basic procedure of various relational degrees method was sketched;Principle and procedure to 11 kinds of grey relational degree was set forth respectively,medical treatment and example of public health index sequence analysis was used to calculation and realization.Implementa-tion step of all methods was given briefly,method principle and information utilization was different.Relational degree result between sequences was in accordance with practical problem.Grey relational degree methods discussion were significant,comparison and selection was awaited to application in health field,and was introduced to some similar research,such as factor selection,comprehensive assessment,sequence analysis and cluster optimization,and so on.
