ECTS - University of Pisa
–a solid background for subsequent exams in this area such as econometrics and applied statistics, in particular within the Official statistics curricula,
–a background of ideas from probability theory and probability modeling
–tools of general statistical reasoning to assist the entire students career and working life.
Given the international nature of the course and the pool of different background at entry, in this course there is a long tradition - unique in this university - of individual and group meetings between the instructor and the students (typically during the first 3 weeks of the course) aimed to allow the instructor to assess the students' initial conditions, the possible presence of entry gaps, and to appropriately define the course targets given the abilities of the audience. The instructor has always encouraged the creation of spontaneous study groups to handle assignments through active discussions between peers.
The final abilities will be assessed by a written exam including both theoretical (e.g., definitions, theorems, proofs etc) and applied questions.
On successful completion of this course students will dispose of a solid background of fundamental statistical theory and ability to implement the methodologies using real or simulated data.
During the entire devlopment of the course day-to-day assignments are foreseen, so that it will be possible for the students as well as for the instructors to have real time update of learning progresses.
To fully benefit of the course (i.e. to develop a feeling of statistical reasoning and attitudes towards the use and interpretation of data) students are strongly recommended to attend lectures intensively, solve assignments regularly, actively participate to open and team discussions.
Very important, given the international status and audience of the course, students will be asked to give availability to provide aid and tutoring to their colleagues from foreign countries.
Day by day.
These are minimal requirements necessary to benefit of the course. Do you fulfill them ? (answer honestly...)
Ex-cathedra lectures using slides complemented by "choke and blackboard" for solving examples and exercises. Day-to-day assignments (to be solved in real time to fully benefit of the course contents). Computer session
How to prepare the exam:
–following lectures actively. Slides are made available a few days after the corresponding lecture on the new e-learning page: https://elearning.ec.unipi.it/course/view.php?id=1015
–doing carefully assignments and exercises (on a day-by-day basis…).
Exercises and assignments are an integral part of the course. They are planned to set in practice the concepts developed day-by-day during lectures, and to follow smoothly the development of the various subjects. Do not neglect them !

Class slides made available within 2-3 days after the corresponding lecture.
Main Course Textbook. Mood AM, Graybill, Boes D (1981), “Introduction to the theory of statistics”, Mc Graw Hill (some editions available online). A very complete reference book. It covers 80% of the course topics. Important you always keep it open in your laptop…
Other readings to be communicated during the Course.
Neither foreseen nor recommended for this course. Anyhow the course materials are largely self-contained.
Information for students unable to attend class lecture due to the COVID situation will follow online activities according to the general rule of this MSE (http://mse.ec.unipi.it/)
To be announced.
