Question:
- State with reason whether the following statements are true, false, or uncertain: [2x5=10] a. Despite perfect multicollinearity, OLS estimators are BLUE. b. In cases of high multicollinearity, it is not possible to assess the individual significance of one or more partial regression coefficients. c. High pair-wise correlations do not suggest that there is high multicollinearity. d. Multicollinearity is harmless if the objective of the analysis is prediction only. e. You will not obtain a high R2 value in a multiple regression if all the partial slope coefficients are individually statistically insignificant on the basis of the usual t test.
