NO.PZ2018101001000050 问题如下 Whiof the following assumptions is least likely part of multiple regression’s? A.The inpennt variables are not ranm. B.The error term is normally stribute C.There is no linerelation between any two or more inpennt variables. C is correct. 考点: Interpret Regression Coefficient, Assumptions anF-test.解析: A和B均属于多元回归的前提假设。C说在两个或多个自变量之间是不存在线性关系的,这句描述是不准确的,应该是不存在一个精确的线性关系,所以应该选择 老师您好,请问下A为什么是错误的,应该怎么理解自变量不是随机的?

NO.PZ2018101001000050 想接着这道题问,残差项服从正态分布,不会导致sericorrelation吗?如果errors之间是correlate,是否意味着errors之间存在某种可以通过formula表示的关系?而服从正态分布随机变量,不一定存在相关关系?
