摘要
本文介绍了关联度分析及其应用,并将该方法与相关分析进行了比较。关联度分析方法可用于卫生系统内部时间序列资料的分析,该方法对数据分布类型、变量之间的相关类型限制较少。通过关联度分析可以找出变量之间的关联程度,为管理和决策提供依据。关联度无负值,如果变量之间发展变化的关系呈负相关时,关联度则不能准确表达。
Incidence degree analysis and application are presented in this article, and, it is also contracted with Pearson and Spearman correlation. Incidence degree could be used to analyse time series data in health system. There is little limit about data distribution and type of variable's correlation. Incidence degree can be found to provide scientific basis for management and decision making through this analysis. Because of no negative value for incidence degree, so, it can not correctly discribe the negative correlation between variables.
