Question Solved in this video:
State whether the following statements are true or false. Give reasons or proofs:
i. In regression through origin models, the conventionally computed R-squared may not be meaningful.
ii. Consider a two-variable Population Regression Function, Yi = B1 + B2 Xi + ui. If the slope coefficient B2 is zero, the intercept B1 is estimated by the sample mean.
iii. In the presence of heteroscedasticity, OLS estimators are biased as well as inefficient.
iv. In a double log model, Ln Yi = A + B Ln Xi + ui , the slope coefficients are different from the elasticity coefficients.
v. The Durbin-Watson d test can also be applied to models that include the lagged value of the dependent variable as one of the explanatory variables
