This document discusses the assumptions of the classical linear regression model (CLRM) and methods for testing violations of those assumptions. It covers the assumptions of no autocorrelation between error terms, homoscedasticity or constant error variance, and the errors being normally distributed. Tests for heteroscedasticity discussed include the Goldfeld-Quandt test and White's test. Tests for autocorrelation examined are the Durbin-Watson test and Breusch-Godfrey test. Consequences of violations include inefficient coefficient estimates and invalid inference. Potential remedies discussed are generalized least squares or using heteroscedasticity-robust standard errors.
Brief notes on heteroscedasticity, very helpful for those who are bigners to econometrics. i thought this course to the students of BS economics, these notes include all the necessary proofs.

Take it to the Limit: quantitation, likelihood, modelling and other mattersStephen Senn
Taking the example of estimating parameter values when some observations are below the limit of quantitation I illustrate the utility of likelihood as a general framework for modelling. Some geometrical representations of this simple problem are considered and the way that the method of maximum likelihood delivers not only an estimate but an estimate of the reliability of the estimate is considered. I also discuss the importance of assumptions about how data come to be missing and some difficulties and limitations for more complex cases will also be touched on.
