【摘要】 任何事物之间都存在着不同类型、不同程度的关联,分析事物之间按什么关系关联、关联程度多大,对问题的研究至关重要.研究两个事物之间是否有关联以及关联程度如何,必须明确以何种关系为研究前提.经典的数理统计理论为线性关联分析提供了有力的依据,但此种方法主要是检验变量之间的线性关联程度,对于变量之间其他关系的检验,应该根据问题的实际需要采用相应的关联分析方法.在比较数据组之间速率变化趋势的基础上得到了速率关联分析法,并以分析城镇居民各项支出与人均工资总收入之间的速率关联程度为例,说明了速率关联分析法的应用.更多还原

【Abstract】 Everything there is correlation of different types,different extent,according to what the relationship analysis between things,much research association,is crucial to the problem.Is there a correlation and the degree of correlation between of two things,must be clear as to what the relationship is the premise of study.Provide a strong basis for the classical statistics theory for linear correlation analysis,but this method is mainly linear degree of correlation test between variables,testing for variables other relation,should according to the actual need of problem by the corresponding correlation analysis method.Based on comparison between groups of data were obtained on the rate change trend rate correlation analysis method,and to rate the degree of correlation between analysis of urban residents per capita wage expenditures and total income as an example,explained the application rate of association analysis.更多还原
