Note: Answer all the questions. While questions in Section A carry 20 marks each, those in
Section B carry 12 marks each.
Section A
1. In the case of a two-variable regression model show that TSS = ESS + RSS. Use
appropriate diagram to explain your result. In this context define the concept of R-squared
and interpret it.
2. a) What is meant by identification problem in a simultaneous equation model?
b) In the following two-equation system check the identification status of both the
equations.
?1 =∝1+∝2 ?2 + ?1?2 + ?1
?2 = ?2 + ?3?1 + ?4?1 + ?5?2 + ?2
c) Explain how the first equation in the above model can be estimated.
Section B
3. What are the limitations of the linear probability model? Explain how the logit model can
be used to overcome these limitations.
4. What are its consequences of heteroscedasticity? How do you detect it? Suggest a method
you would follow to remove the heteroscedasticity problem in a dataset.
5. What are the advantages of dummy variables in a regression model? What is dummyvariable trap? Formulate a regression model with intercept and slope dummies.
6. Suppose the explanatory variable in a regression model is measured with error. What are its
consequences? What steps will you take to solve the problem?
7. Write short notes on the following:
a) Sampling distribution and standard error
b) General Least Squares model
