一般没什么关系,因为交互项是两个或者两个以上的变量相乘得出的,这个交互项与其他变量不存在线性关系,存 ...
To test the moderating hypotheses (Hypothesis3–6), we added the interaction terms in Models M1* and M2* (see Tables 2 and 3). To deal with multicollinearity between the interaction terms, we mean centered each scale that constitutes an interaction term and created the interaction terms by multiplying the relevant mean-centered scales.
能看下这句话吗? 为了解决交互项之间的多重共线性?这里 交互项不就和多重共线性有关联了吗? 另外,谁能翻一下这句话,不太懂这句话什么意思
