Question
Regarding Brent's Statements 1 and 2:
Answer Choices:
A. Both statements are correct
B. Only Statement 2 is correct
C. Only Statement 1 is correct
Explanation
Statement 1 is correct. Comparing the formulae for computation of AIC and BIC, because ln(n) is greater than 2 for even small sample sizes, the BIC metric imposes a higher penalty for overfitting. Statement 2 is correct. Both AIC and BIC evaluate the quality of model fit among competing models for the same dependent variable. Lower values indicate a better model under either criteria. AIC is used if the goal is to have a better forecast, while BIC is used if the goal is a better goodness of fit.
