Obiettivi formativi
The course will be divided in two parts, Multivariate statistics and Computational Statistics.
The first part takes up the concepts of multivariate statistical analysis, regression and classification techniques, but introduces a robust approach. Furthermore, Bayesian networks will be presented. During the course applications to real situations will be presented, the statistical packages as FSDA toolbox for MATLAB and R libraries will be used.
The second part will focus on advanced computational statistics for simulation-based analysis and introduce students to basic concepts, techniques and applications of computational statistics to be used in finance and economics. Students will be also introduced to a basic knowledge of statistical software and programming (R, Python and OpenBUGS) for Monte Carlo simulation in order to solve practical problems.
Risultati apprendimento attesi
Students will achieve skills for doing independent study and research, alsoin presence of outliers and deviation form the classical hypothesis. Moreover they will learn computational ans symulation techniques. At the end they will also able to use a variety of different software for advance statistical analsysis.

Prerequisiti
No mandatory prerequisites are required, but a good knowledge of statistics and probability fundamentals is strictly reccomended. Matrix algebra and calculus will be beneficial but are not strictly required. Basic programming skills are also useful.

Materiale di riferimento
Suggested reading for insights into some topics in main textbooks:
(i) Introducing Monte Carlo Statistical Methods with R (2010) by C.P. Robert, G. Casella, Springer.
(ii) The BUGS book (2010) by Lunn et al., Taylor & Francis
(iii) Exploring multivariate data with the forward search (2013) by Atkinson, Riani and Cerioli, Springer

Further reading will be suggested during the course.
Other material:
Slides presented in class, Sceintific Papers, Maltab scripts, R scripts, Python notebooks, OpenBUGS files
Modalità di verifica dell’apprendimento e criteri di valutazione
Some assignments will be delivered and evalueated during the course and a written final project is required. Evaluation of the project will be performed through an oral presentation and examination, in which students will be asked questions about the methods used in the project, the code produced and on the rest of the syllabus.
