Compare the following two regressions
Wed 19 Sep, 2012 05:08 pm - 1) Yᵢ = B^0 + B^1Xᵢ + eᵢ 2) Yᵢ = B^0 + B^1(2Xᵢ) + eᵢ (B^0= beta hat 0) (ᵢ is subscript i) Equation i. is exactly the regression we’ve been working with thus far, so all... (view)
Prove that ŷ0 is an unbiased estimator of Y0.
Wed 19 Sep, 2012 04:50 pm - Also: Derive the formula for the variance of ŷ0 a. Hint 1: You are looking for Var(Y^0)=Var(B^0+B^1X0). This is the variance of a sum of two random variables. What is the general formula for such... (view)
