What is the meaning of the term "heteroscedasticity"? A. The variance of the errors is not constant B. The variance of the dependent variable is not constant C. The errors are not linearly independent of one another D. The errors have non-zero mean 4. What would be then consequences for the OLS estimator if heteroscedasticity is present in a regression model but ignored? A. It will be ignored B. It will be inconsistent C. It will be inefficient D. All of a),c), b) will be true. 5. Which one of the following is NOT a plausible remedy for near multicollinearity? A. Use principal components analysis B. Drop one of the collinear variables C. Use a longer run of data D. Take logarithms of each of the variables 6. What will be the properties of the OLS estimator in the presence of multicollinearity? A. It will be consistent unbiased and efficient B. It will be consistent and unbiased but not efficient C. It will be consistent but not unbiased D. It will not be consistent 7. A sure way of removing multicollinearity from the model is to A. Work with panel data B. Drop variables that cause multicollinearity in the first place C.
