Competences and skills that will be acquired and learning results:
Once successfully having studied this subject, the students should be able to:

- Analyze problems involving random phenomena
- Define populations for a statistical study
- Build Hypothesis about a distribution
- Test hypothesis about the paramters of the chosen model
- Evaluate how well does the model fit to reality
- Understand the limitations of the methods that have been studied and the conditions under which they lead to wrong conclusions Ability to work in a team.

6. Linear regression
6.1 Introduction

Learning activities and methodology:

- Lectures: introducing the theoretical concepts and developments with examples, 2.2 ECTS
- Problem solving sessions: 2.2 ECTS
- Computer (practical) sessions: 0.6 ECTS -- 4 SESSIONS
- Evaluation sessions (continuous evaluation and final exam): 1 ECTS

Assessment System:

There will be continuous evaluation by means of two partial examinations. There will be some questions about the computer sessions at those exams.

If the grade obtained at the continuous evaluation is higher than 5, the student should not attend the final exam and his/her final grade will be the grade of the cotinuous evaluation.

If the grade obtained at the continuous evaluation is lower than 5, the student will have to attend the final exam. For those students, the final grade will be computed giving a 40% weight to the partial examinations, and a 60% weight to the grade at the final exam.

The grade for the students attending the extraordinary examination will be the grade obtained at such exam.
