EXAM DESCRIPTION

The exam is written and online until the end of the COVID-19 emergency. Further information about the examination will be provided on AulaWeb.

ASSESSMENT METHODS

The written examination verifies that the student has acquired and knows how to use the basic tools of probability theory (random variables, random vectors, functions of random variables, limit theorems) and statistics (estimators, hypothesis testing)
