questions about the consequences of the measurement error: 1. The bias of the OLS estimator for B2 is 2. The variance of the OLS estimator for dy is increased by a factor of
Suppose that the true model is Q=B₂X+u where u has zero mean and constant variance 2. However, Q is measured with measurement error t, and the observed independent variable is Y=Q+u Assume that has zero mean and constant variance 5, and it is distributed independently of u. Q and X. Answer the following two
