Question 1
A researcher wants to estimate a model with the dependent variable, Y, and three explanatory variables X2, X3, and X4.She suspects that time-varying heteroscedasticity will be an issue with her data, and decides to estimate a higher-order GARCH model.In particular, she estimates a GARCH(2,1) model.
Question 2
The researcher’s colleague wants to estimate a different GARCH model using the same data variables.He believes that a higher-order GARCH model is not sufficient and that a GARCH-in-Mean or a TGARCH model would be a better choice.
