摘要
本文介绍了倾向值分析的基本原理和分析过程,并使用该方法分析老年人的工作类型与认知能力之间的关系,通过减少相关混淆变量对工作类型干预效果的影响保证因果关系的可靠性。结果表明,经过倾向值匹配后不同工作类型的个体差异得到一定程度的消除,分层分析中不同工作类型对认知能力的平均影响不显著,但t检验下不同工作类型对认知能力的影响显著。
in this paper,the basic principle and analysis process of the propensity score analysis are introduced.Using The method is used to analysis the relationship between the job type and cognitive ability of the aged.By reducing the influence of the related confounding variables on the effect of ob type,the reliability of causality is guaranteed.Results show that the individual differences of different types of work after the propensity scaore matching can be eliminated to a certain extent.Although the average effect of different types of work on cognitive ability was not significant,the influence of different work types on cognitive ability was significant under Student s t test.
