Conoscenze e abilità da conseguire

By the end of the course the student knows the fundamentals of the most important multivariate techniques to build supervised statistical models for predicting or estimating an output based on one or more inputs. The student is able to represent and organize knowledge about large-scale data collections, and to turn data into actionable knowledge.

Metodi didattici

Lectures and practical sessions.


Modalità di verifica e valutazione dell'apprendimento

The learning assessment is composed by a written test lasting 70 minutes. The written test is aimed at assessing the student's ability to use the learned definitions, concepts and properties and in solving exercises. During the written exam, students can only use the cheat sheet that is provided on virtuale.unibo.it, containing references to R packages and functions. Students cannot make use of the textbook, personal notes and mobile phones (smart watch or similar electronic data storage or communication device are not allowed either).

The written test consists of 5-7 questions, both multiple choice and open, some of which to be solved in R. The final grade is out of thirty.

Students that, despite having passed the exam, do not feel represented by the obtained result can ask to have an additional (optional) oral exam that can change the grade by +/-3 points.

Strumenti a supporto della didattica

The following material will be provided: slides of the lectures, exercises with solutions, mock exam.
