Statistical Methods in Econometrics


The aim of this course is to present modern econometric methods in a unified form. The central statistical theory will be the theory of extreme estimators and the consequent theory of test methods and confidence regions. This general theory will be applied to the non-linear least squares method, the maximum likelihood and pseudo-maximum likelihood methods and the generalised moments method, as well as the asymptotic least squares method. Applications to a variety of models will be considered.
