This is a graduate level introductory course in mathematical probability and statistics: its objective is to provide students with key conceptual tools that are necessary for additional training in econometrics and microeconomics. Beginning from basic axiomatic definitions of probability, the course introduces univariate and multivariate probability distributions, samples and statistics, concepts of estimation and inference, some key asymptotic results, and it concludes with an introduction to linear projections and regression, whose properties are emphasized in preparation for further coursework in econometrics.

The final evaluation for this course is determined as follows: a midterm exam accounts for 30% of the grade; a final exam counts for 50%, while the remaining 20% is based on the performance in regular assignments with an approximately biweekly expected cadence |
