Answer all the questions
Section I: Long answer questions (word limit – 500 words). Each question carries 20 marks.
Word limit does not apply in the case of numerical questions.
- (a) Distinguish between the Population Regression Function and Sample Regression Function in detail. Use appropriate diagram to substantiate your response.

Word limit does not apply in the case of numerical questions.
- Differentiate between Chi-square distribution and t-distribution.
- What is an estimator? Explain all the properties of an estimator with reference to BLUE.
- Two variable regression model could have three functional forms as given below:
?i = ?1 + ?2?i + ?i
???i = ?1 + ?2?i + ?i
