Statistics for Economics and Business
Description
This course provides a foundation in probability and statistics and introduces basic regression analysis. In probability theory, we cover the basic concepts from probability spaces over random variables up to convergence. This theoretical equipment is needed for inductive statistics and regression analysis that aims at drawing conclusions from samples about causes and regularities underlying the population.
Compétences visées
- Familiarity with the basic concepts in probability, statistics, and regression analysis : awareness of theoretical knowledge and first experience in handling and describing data, estimation, and testing using the software R, Stata and Mathematica
- Capacity to compile basic descriptive, and to formulate and test hypothesis about the data generation process, including basic regression analysis
Modalités d'organisation et de suivi
The course includes 30 hours of lecturing (‘cours magistral’). Group exercises need to be handed in on a regular basis. Exercises include pen and paper exercises but also R-programs in which data is analyzed and theoretical concepts are exemplified through simulation. Main teaching materials are the lecture blackboard/slides, textbooks (see Main references), and computer programs in R, Stata and Mathematica.
