Learning objectives

The course is aimed at a significant deepening of some statistical models of particular relevance to management engineering: the multiple regression model, time series analysis, and forecasting models. Learning the MATLAB language is an integral part of the course.

Course unit content

The course includes theoretical lessons and exercises. The course topics will cover:

Deepening understanding of regression: from the regression line to the simple regression model; from the simple regression model to the multiple regression model.
Time series: from independent data to dependent data; preliminary transformations and models.
Forecasting: using estimated models to obtain projections and forecasts.
From theory to practice: using software (MATLAB) for statistical processing.

Assessment methods and criteria

Oral Exam.
In the exam, the student must demonstrate knowledge of the various theoretical models indicated in the program and developed during the course. Proficiency in the MATLAB language is an essential requirement. The interview can be conducted, at the student's choice, through the discussion of a Project Work developed by writing a MATLAB program.
