问题如下：

8.If Varden’s beliefs about ROE and CEO tenure are true, which of the following would violate the assumptions of multiple regression analysis?

选项：

A.

The assumption about CEO tenure distribution only

B.

The assumption about the ROE/dividend growth correlation only

C.

The assumptions about both the ROE/dividend growth correlation and CEO tenure distribution

解释：

C is correct. Multiple linear regression assumes that the relationship between the dependent variable and each of the independent variables is linear.

Varden believes that this is not true for dividend growth because he believes the relationship may be different in firms with a long-standing CEO. Multiple linear regression also assumes that the independent variables are not random. Varden states that he believes CEO tenure is a random variable.

同学你好，直译即可。X变量不能是随机变量。这是回归假设之一

NO.PZ201709270100000308 8.If Varn’s beliefs about ROE anCEO tenure are true, whiof the following woulviolate the assumptions of multiple regression analysis? The assumption about CEO tenure stribution only The assumption about the ROE/vingrowth correlation only The assumptions about both the ROE/vingrowth correlation anCEO tenure stribution C is correct. Multiple lineregression assumes ththe relationship between the pennt variable aneaof the inpennt variables is linear. Varn believes ththis is not true for vingrowth because he believes the relationship mfferent in firms with a long-stanng CEO. Multiple lineregression also assumes ththe inpennt variables are not ranm. Varn states thhe believes CEO tenure is a ranm variable. 这道题的解析当中这句话是否可以理解为自变量X1，X2。。。。不能是随机变量，因为在多元回归当中自变量之间是没有相关性（或者相关性比较低），否则就会违反多重共线性。
