Which of Vasileva's assumptions regarding regression analysis is incorrect?
选项:
A. Assumption 1
B. Assumption 2
C. Assumption 3
解释:
C is correct. The assumptions of the linear regression model are that
(1) the relationship between the dependent variable and the independent variable is linear in the parameters b0 and b1,
(2) the residuals are independent of one another,
(3) the variance of the error term is the same for all observations, and
(4) the error term is normally distributed.
Assumption 3 is incorrect because the dependent variable need not be normally distributed.
因变量不能是正态分布,是这个意思吗,可以当结论记下来吗
