Sample Properties of the Least Squares and Instrumental Variables Estimators

Large-Sample Properties of the Least Squares and Instrumental Variables Estimators [Pg.14]

For the classical regression model y = XP + with no constant term and K regressors, what is [Pg.14]

be the rth residual in the ordinary least squares regression of y on X in the classical regression model and let s, be the corresponding true disturbance. Prove that plim(e, - e,) = 0. [Pg.14]

For the simple regression model, v, u + s s, N(0,a2), prove that the sample mean is consistent and [Pg.14]

For the model in (5-25) and (5-26), prove that when only x is measured with error, the squared correlation between y and x is less than that between y and x. (Note the assumption that y = y.) Does the same hold true ify is also measured with error  [Pg.15]
