The exam is divided in two parts: a written test to be carried out in the classroom and a homework to be carried out individually. The exam mark consists of the weighted average of the marks in the written test and in the homework, weighed respectively by 75% and 25%.
The written test is conducted in online mode, lasts two hours and will contain both practical exercises and theoretical questions. During the test it is possible to use the calculator and the statistical tables, but not notes or other didactic material.
The homework consists in a MATLAB application of the linear regression model to be delivered in pdf format.
