Intended Learning Outcomes (ILO)
KNOWLEDGE AND UNDERSTANDING
- Recognize the key guiding principles and concepts of statistical inference.
- Identify and describe a toolkit of methods and models.
- Summarize and defend concepts and knowledge useful in preparation of the courses on Machine Learning and Artificial Intelligence.
APPLYING KNOWLEDGE AND UNDERSTANDING
- Formulate suitable probabilistic models for statistical problems in the health sciences.
- Apply appropriate statistical methodology to estimation and testing problems.
- Interpret the outcome of the estimation procedures in view of the application at hand.
Teaching methods
- Lectures
- Practical Exercises
DETAILS
- Face-to-face lectures. Theory, exercises, and some R will be blended during the lectures.
- PC-based labs ("Bring Your Own Laptop"). Labs will be devoted to exercises and hands-on sessions to appreciate the concepts and work on examples, also using the R programming language.

ATTENDING AND NOT ATTENDING STUDENTS
- A 2-hour in-class, closed book and closed notes exam will be held after the course, within each of the three exam sessions.
- The exam will be handwritten on paper.
- Some of the questions (for a total of 21 points out of 31) will cover the methods, models, and properties discussed in class, to assess the understanding of the theoretical aspects.
- Some of the questions (for a total of 10 points out of 31) will require the analysis of some data using R. Students will bring their own laptop to the exam and will not be required to submit any of the code or output: only the final answers of the analyses and the associated comments will need to be reported on the paper. No access to the internet will be allowed during the exam.
- There will be no difference in assessment method / exam program between attending and non attending students.
NOTE: While there will be no difference in assessment method / course content between attending and non attending students, attendance is strongly recommended.
