And what I'm going to do is form statistical matched pairs between families that are nearly identical on every dimension that I can measure, and then I'm going to explore whether or not the link between language and savings holds What are the characteristics we can control for?
我接下来要做的就是通过统计匹配的方式 找到各个方面都近似相同的家庭， 然后去看看在控制了这些变量之后 语言和储蓄之间是否还存在着联系。 我们能够控制那些特征？
