PART III: Relaxing the assumptions of the classical linear regression model
Lecture 7: The aim of this lecture is to analyse the problem of heteroskedasticity.
By the end of it students should be able to:
• Summarize the sources of heteroskedasticity
• Illustrate the consequences of heteroskedasticity for OLS estimators and their variances
• Detect heteroscedasticity using formal and informal methods
• Apply remedial measures for heteroskedasticity
Main text reading: DG Chapter 11.

Lecture 8: The aim of this lecture is to analyse the problem of autocorrelation.
By the end of it students should be able to:
• Summarize the sources of autocorrelation
• Illustrate the consequences of autocorrelation for OLS estimators and their variances
• Detect autocorrelation using formal and informal methods
• Apply remedial measures for autocorrelation
Main text reading: DG Chapter 12.

Lecture 9: In this lecture we will analyse various issues related to multicollinearity, non-linearity and non-stationarity.
By the end of it students should be able to:
• Summarize the sources of multicollinearity
• Illustrate the consequences of multicollinearity for OLS estimators and their variances
• Distinguish between intrinsically linear and non-linear regression models
• Contrast stationary with non-stationary processes
Main text reading: DG Chapters 10, 14, 21.
