solve both parts
Given the true model: Y = Bo + B1 * X1 + B2 * X2 + u and our estimating model: Û = ỹ = Bo Bot Bi *X + and that B2 =-5 and cov(X1,X2)=3. What direction would the bias of B, be in? O Positive Bias O No Bias Negative Bias
Given the true model: Y = Bo + B1 * X1 + B2 * X2 + u and our estimating model: ŷ = Bo + ß* x + for which of the following conditions would ß not equal Bi ? O BE = -2, cov(X1,X2) = 0 O B2 = 0, cov(X1,X2) = 1 B2 = 0, cov(X1,X2) = 0 B2 = -2, cov(X1,X2) = 1
