Metodi didattici
Modalità di verifica e valutazione dell'apprendimento
Final examination consists of a written test and a practical project. The written test aims at verifying the general theory behind the studied statistical methods, application of the methods learned in the course to data and interpretation of results. The practical project aims at verifying R knowledge and it will deal with a real ecological/environmental problem that might be solved using R-software. The practical project will be discussed through an oral presentation.
Strumenti a supporto della didattica
Lecture notes, slides, R scripts and additional material posted on virtuale.
