Question

Question 19 3 pts The ordinary least squares estimator of a slope coefficient is unbiased means if repeated samples of the same size are taken, on average the OLS estimates will be equal to the true slope parameter O the mean of the sampling distribution of the slope coefficient is zero. O the estimated slope coefficient will always be equal to the true parameter value. the estimated slope coefficient will get closer to the true parameter value as the size of the sample increases. D Question 20 3 pts In regression analysis, which of the following statements is true? O A researcher can compute both the disturbances and the residuals. A researcher cannot compute either the disturbances or the residuals. A researcher can compute the residuals but not the disturbances. O A researcher can compute the disturbances but not the residuals.

Answer 1

19)A) If the repeated sample of same size are taken on average OLS estimates will be equal to true slope parameter. Explanation - The estimate is said to be unbiased estimate if repeated sample size are taken the mean value is equal to true parameter.

20)C) A researcher can compute residuals but not disturbances Explanation- The errors ( disturbances) are unobservable however residuals are oberservable hence residuals can be computed but not disturbances.
