请问这个考察的是多重共线性中的哪一个点呢？刚刚看正文都没有找到chu'chu，很神奇
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。
