The course starts with a discussion of the logic of the multivariate regression model and the central assumptions underlying the ordinary least squares approach. This part includes an extensive discussion of the derivation of the ordinary least squares estimator, its standard error and summary statistics. Then it proceeds with testing for the adequacy of the assumptions and suitable corrections and extensions to the estimation techniques in the context of cross-sectional data. Particular emphasis will be laid on influential cases, multicollinearity, heteroskedasticity, and autocorrelation. Finally, categorical predictors, interactions, and nonlinearities will be considered.
