- * 自变量x 因变量 y 调节变量m
- * #1 汇报标准系数
- reg y c.x##c.m age gender , r beta
- * #2 变量标准化 z_为前缀
- reg z_y c.z_x##c.m z_age gender , r
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?
