This linked module reviews basic concepts of probability, statistical theory and methods introduced in the first year modules. They develop ideas of random variables, sampling, estimation, hypothesis testing and related aspects of inferential methods in more detail. Two variable and multiple regression models are developed and estimation procedures considered under the classical assumptions as well as violations of these assumptions. Applications to empirical economics are introduced to link the statistical and econometric methods to a range of problems in economics. Weekly problem classes and computer laboratory sessions support the lectures.
