关于调节效应中心化和标准化的问题,论坛里有个帖子(https://bbs.pinggu.org/thread-11226829-1-1.html)写得特别清楚,
要么对X/Y/M中心化,要么对所有变量标准化。但我还有个stata命令相关的问题:变量标准化和汇报标准系数有什么区别呢?
查询网页得到:Beta coefficients are the result of
standardizing both the independent and dependent variables before running the regression analysis. They provide a measure of the strength and direction of the relationship between the independent variable(s) and the dependent variable, with all variables measured on the same scale.
是这个差别吗?
所以如果汇报标准化系数最好是 #2 这种吗,大家一般是什么时候/怎么用的beta选项的呀?
