OVERVIEW

The course aims at providing a thorough account of classical and modern statistical inference at an intermediate level, focusing both on the classical likelihood method and on simulation techniques. Then, the theory and applications of regression and classification models will be introduced, with special attention to socio-economic applications.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to provide a precise overview of statistical inference at an intermediate level. The first part concerns classical mathematical statistics, based on likelihood, with some hints on techniques based on simulation. The second part focuses on the main regression and classification techniques. The topics covered and the examples presented will allow students to autonomously. deal with data analysis problems in different contexts and to understand the fundamentals of statistical models currently used in economic applications.

AIMS AND LEARNING OUTCOMES

The course is divided into two parts:

                1) Some topics in classical inferential Statistics: the main families of univariate and multivariate distributions, the likelihood and its properties, simulation and the bootstrap.

                2) Statistical models for classification and regression. Multiple regression, generalized linear model theory, logistic regression and regression for count data, nonparametric techniques. Nonparametric techniques. Model selection techniques.

All the topics will be accompanied by practical exercises in R, so that the student can also combine the understanding of the theory with the ability to apply correct statistical analyses in real contexts and to read correctly the output of the statistical procedures.

Knowledge and understanding: Students will know the main techniques and the main tools for inferential statistics. They must be able to frame these tools in general terms (both theoretical and applied), and to analyze the underlying mathematical and statistical background.

Ability to apply knowledge and understanding: Students will be able to identify, when faced with problems from different contexts, the correct analysis. Moreover, they will be able to evaluate the results obtained through statistical software.

Making judgments: Students will have to become aware of the potential and limits of the statistical techniques, through the analysis of examples and case studies.

Communication skills: Students must be able to use the correct technical statistical language for the communication of the results and for the description of the techniques.

Learning skills: Students will develop adequate learning skills in order to continue with further studies about other aspects of the subject and different fields of application than those illustrated. Furthermore, they must also be able to use the R software in a general context.

EXAMS

EXAM DESCRIPTION

The exam is a written exam which consists of three parts:

1) a general essay question

2) one or more questions on specific topics

3) a comment on a R output.

The complete exam rules will be available on the class Aulaweb page. For attending students, intermediate exams based on R exercises will be organized. Such intermediate exam will replace the complete exam.

ASSESSMENT METHODS

As far as possible, the questions of the written exam are chosen in order to cover all the topics of the course. The general question aims at assessing the degree of knowledge of the subject and the acquisition of the correct technical language, the specific questions are aimed at assessing the critical ability of the student, while the purpose of the comment to the output is to evaluate the application capabilities.
