1. Consider the following simple regression model without intercept: y = B1x + u. Assume that the standard assumptions about this model apply. a) Derive the ordinary least squares (OLS) estimator of ß1. b) Derive the expected value of the OLS estimator Pi Is Pi an unbiased estimator of B1 ? c) Derive an expression for the variance of Note: 1. ß1 menas beta one. 2. means beta one hat. 1.
