3.1.4.0 SUMMARY
This unit begins with a general discussion ofheteroscedasticity and its meaning. Also discussed are the reasons why the distribution of a disturbance term maybe subject to heteroscedasticity, and the consequences of the heteroscedasticityproblem for OLS estimators. We continued with presentation of several tests for heteroscedasticity and methods of alleviating the problem.
3.1.5.0 CONCLUSION
The discussion in this unit concludes with an awareness to the students that the concept of heteroscedasticity and associated problems are indications of how an apparent case of heteroscedasticity maybe caused by model misspecification.
