Learning Outcomes

By the end of this course the student will be able to:

  • Have basic knowledge of theoretical probability distributions which constitute an essential methodological tool.
  • Understand and be able to apply essential statistical inference. This implies that students should develop critical thinking on decision making.
  • Understand and apply basic regression analysis to decision making

By the end of this course the student will have developed the following skills:

  • Ability to exhibit knowledge and understanding of the essential facts, concepts, theories and applications which are related to statistical inference and regression analysis.
  • Ability to adopt and apply methodology for solving problems in the fields of statistical inference and regression analysis.
  • Ability to use computational techniques in the aforementioned fields.
  • Ability to interact with experts in statistics.
