Given the true model: Y = Bo + B1 * X1 + B2 * X2 + u and our estimating model: ŷ = 80 + ß *X + for which of the following conditions would â not equal Bi ? BL = -2, cov(X1,X2) = 0 B2 = 0, cov(X1,X2) = 1 O B2 = 0, cov(X1, X2) = 0 O B2 = -2, cov(X1,X2) = 1
Given the true model: Y = Bo + B1 * X1 + B2 * X2 + u and our estimating model: л ŷ = Bo + 8 + x + and that B2 =-5 and cov(X1,X2)=3. What direction would the bias of Bibe in? O Positive Bias O No Bias Negative Bias
