4. If Y is measured with error and X is correlated with the error term, then a. there is an attenuation bias b. there is a bias c. the standard error needs to be corrected d. the model is not iid e. none of the above
Added by Luis Miguel M.
Step 1
The question involves a situation where the dependent variable \( Y \) is measured with error, and the independent variable \( X \) is correlated with the error term. This scenario is common in econometrics and can lead to various biases in estimation. Show more…

26. Heteroscedasticity may arise due to various reasons. Which one of these is NOT a reason? a) Extremely low or high values of X and Y coordinates in the dataset b) Correlation of variables over time c) Incorrect specification of the functional form of the model d) Incorrect transformation of variables 30. In a regression model with multicollinearity being very high, the estimators a) Are unbiased b) Are consistent c) Standard errors are correctly estimated d) All of the above

4. In order to use the linear regression model, we need assumptions about the error term. Which of the following assumptions is not one of the assumptions? a. The error term, εi is presumed to be a normally distributed random variable. b. The mean, or expected value, of the error term is non-zero (E(εi) ≠ 0). c. The variance of the error term is constant, denoted by σε^2. d. The errors are assumed to be independent of each other. e. All of the above.
