1.1 -- Which of the following assumptions is not needed for 3 to be an unbiased
estimate of the population parameter in the regression model
y = a + B₁x₁ + B2₂x₂ + Ui
where a is the intercept term, ß is the slope parameter, and u is the unobserved error
Jerm?
A. The variance of the error term is homoskedastic, i.e. var (u|x₁, x₂) = 0².
B The variable, x₁ and x2, are mean independent of the error term. E[ulx₁, x₂] = 0. m
C. No perfect collinearity
D. We have a random sample of size n from the underlying population
