如何理解relationship,correlation和association之间的区别

已有 309 次阅读2022-12-11 11:21 |个人分类:科研笔记|系统分类:生活笔记

  relation/relationship 关系,联系,往来;常常在文章中用作the relation/relationship betwwen A and B relationship 更强调关系,比如说男女的暧昧关系、

  relationship和Relation不能相互替换:

  These are not interchangeable. "Relationship" is used to describe a social bond, such as between a mother and a child, a teacher and a child, etc. "Relation" is used to describe non-animate associations, including those between variables.

  correlation,correlation的两边是变量(常为continuous data),表示的是两个变量相互之间的变化关系(正相关或负相关),如:Birth weight is positively correlated with maternal body.

  association的两边往往是原因和结果(常为categorical data),表示的是二者之间的因果关系,如:

  Male sex and smoking are associated with squamous carcinoma.

  这个association是通过卡方检验(涉及categorical data的组间差异比较)和logistic回归分析(因变量是categorical data)得出来的

  总结:

  1、因果联系的话,使用association。

  2、relation用来刻画两个变量之间的关系。
