GUIDELINES FOR TERM PAPER
- due date: Nov 25,2011
- Put a hard copy in my mailbox, which is at the first floor near elevator with my name “???”on it. My mailbox is at about 2nd row from bottom and in the middle.
- Identical term paper would not be accepted.
The following content should be included.
1 Introduction (Background and Purpose)
2 Multiple regression
2.1 Data source
2.2 Model specification (The model here should be the best model, see section 5.2)
2.3 Result report (estimated equation, interpretation of coefficient, significance of explanatory variables, explain the meaning of R-squared and F value showed in Stata outcome)
2.4 Conclusion
3 Omitted variable bias3.1 Drop one of explanatory variable from original multiple regression and report estimation result. Explain changes in estimated coefficients (why it changes a lot or why it changes a little, it is upward or downward bias)
3.2 Name a variable excluded from your original model and state the possible impact on estimated coefficients.
4 t test , F test and LM test4.1 Test the significance of one independent variable with t, F (in terms of SSR), F (in terms of R
2) and LM test.
4.2 Test, where is value you choose other than zero.
4.3 Test a multiple hypothesis other than joint exclusion of
all
independent variables
5 Functional form5.1 For at least 3 different functional forms, such as log-log, log-level, level-log, quadratic form, interaction term and inverse terms, report regression outcomes and interpret estimated coefficients.
5.2 Choose best model among above models and give reasons, which can not be “I think”.
6 Prediction
For a set of particular values of independent variables, give the estimate of and its 95% CI.
7 Heteroskedasticity7.1 Perform BP test (hint: estat hettest)
7.2 Report estimated equation with heteroskedasticity-robust standard error (hint: reg y x, robust)
