**Salvatore Ruggieri**- Università di Pisa
**Office hours:**Wednesdays h 14:00 - 16:00 or by appointment, at the Department of Computer Science, room 321/DO, or via Teams.

Lessons will be also live-streamed on the Teams space.

Students should be comfortable with most of the topics on mathematical calculus covered in:

**[P]**J. Ward, J. Abdey.**Mathematics and Statistics**. University of London, 2013.*Chapters 1-8 of Part 1*.

Extra-lessons refreshing such notions may be planned in the first part of the course.

The following are *mandatory text books*:

**[T]**F.M. Dekking C. Kraaikamp, H.P. Lopuha, L.E. Meester.**A Modern Introduction to Probability and Statistics**. Springer, 2005.**[R]**P. Dalgaard.**Introductory Statistics with R**. 2nd edition, Springer, 2008.- selected chapters of other books for advanced topics

- The project can be done in groups of at most 3 students.
- The project must be delivered (report + code) by end of July.
- The oral discussion must be done by the September session, and it will cover both the project and all topics of the course.
- The project replaces the written exam but
**students have to register for the written dates in order to fill the student's questionnaire**. - Groups ready to discuss send the project to the teacher plus availability time slots for oral discussion.

* There are no mid-terms.* The exam consists of a written part and an oral part. The written part consists of exercises on the topics of the course. Each question is assigned a grade, summing up to 30 points. Students are admitted to the oral part if they receive a grade of at least 18 points. Written exam consists of open questions and exercises. Example written texts will be added here. Oral consists of critical discussion of the written part and of open questions and problem solving on the topics of the course.

Registration to exams is mandatory (**beware of the registration deadline!**): register here

Lessons will be live-streamed on the Teams space and recorded.

To watch the recordings online, you must be connected to the unipi.it VPN. Alternatively, right click on the link and download the whole file, then watch it locally on your computer.

Slides and R scripts might be updated after the classes to align with actual content of lessons and to correct typos. Be sure to download the updated versions.

This course of 9 ECTS replaces an older 6 ECTS version.

The 6 ECTS version is discontinued. Students having the 6 ECTS version in their study plan can still take the 6 ECTS version exam for the A.Y. 2021/22, 2022/23 and 2023/24. However, there will no specific project for the 6 ECTS version.
