The course covers the basics of statistical modelling with the software Stata. Much emphasis is placed on the linear regression model, tackling issues in specification (non-linear functions, interactions, selection of covariates) and model checking (collinearity, heteroscedasticity, outliers). The course also covers logit/probit models for binary and ordinal responses and multilevel linear models. The ideas are illustrated through the analysis of real data using Stata.
