Course objectives

General Objectives The course provides students with the necessary knowledge to understand the main statistical methodologies useful to formulate, estimate and validate linear regression models and for discrete data. Particular emphasis will be given to applications in the business, socio-economic and financial fields, aimed at the analysis of specific business management problems and the evaluation and control of business processes. Through case studies, classroom exercises and group work, students will learn how to use the statistical software R, not only as a working tool, but also as a tool of deepening the theoretical models and their applicability to real data. Furthermore, starting from the analysis of real data, students will acquire the ability to discriminate between alternative statistical procedures, evaluating their advantages and disadvantages, as well as to critically read and understand scientific articles that make use of procedures that are not illustrated in the course. Specific Objectives Knowledge and understanding: The course provides students with the knowledge to specify and estimate a regression model and to interpret the results of an estimation procedure. Applying knowledge and understanding: Through classroom exercises, case studies and group work, the course supports students in carrying out an empirical analysis using statistical software. At the end of the course, students will be able to study the relationships between two or more variables (qualitative and/or quantitative), explain the variability observed in the data and critically analyse the results obtained. Making judgements: The content and methods of the course enable students who successfully pass the examination to acquire a sensitivity to empirical data analysis; using the methodological tools introduced in the course, students will be able to discriminate between different statistical procedures and to critically evaluate the results. Comunicaton skills: The course also contributes to strengthen oral exposition and synthesis skills, as attending students are invited to carry out group work, the results of which are to be summarised in a short report and publicly presented to all other students. Learning skills: The course guarantees the acquisition of a high level of autonomy in the management of study and learning. This is made possible through classroom activities which, starting from real problems, encourage students to evaluate the advantages and disadvantages of the procedures adopted, providing them with the appropriate approach for the autonomous understanding of alternative statistical models, not introduced in the course, and their evaluation in terms of advantages and limitations.

Course program
Introductory recalls on the main concepts of statistical inference. Explanation of a phenomenon as a function of one or more concurrent phenomena: statistical regression models. The case of continuous dependent variable and the linear regression model (simple and multiple). Inferential procedures in linear regression analysis. Misspecification tests. Case study and identification of specification problems in it. The case of limited dependent variables and the corresponding nonlinear models: the binary response model for binary dependent variables; the ordered response model for dependent variables with multiple ordered categories; the multinomial model for dependent variables with multiple unordered categories; the Poisson model for discrete quantitative dependent variables (with count values) and its possible generalizations (ZIP and Hurdle models). Some notions of panel data models and time series analysis. The time devoted to each part of the program may vary from time to time depending on the students' feedback. For attending students, an essential part of the lectures is the use of the R statistical software in the laboratory, which takes at least a third of the lectures
Prerequisites
Basic statistical course and basic notions of calculus
Books
A possible textbook will be indicated later, before the start of the course. In any case, students may refer to the materials provided by the lecturer.
Frequency
Attendance is not mandatory and is expected to be in presence
Exam mode
The evaluation aims to assess the knowledge acquired by the student, his skills in explaining theoretical concepts using the appropriate terminology, in quantitative analysis of real data (applying the most appropriate statistical tools) and in the critical interpretation of the results obtained in the statistical analysis. The evaluation is based on a written exam and a short oral exam. Instead of the written exam, attending students can take part in a project, aimed at the analysis of real data, to be completed with the drafting and presentation of a short paper. The written exam, lasting two hours, includes exercises, closed form questions and possibly open form questions. In particular, multiple-choice questions aim to test skills in the interpretation and in the critical evaluation of the results obtained applying statistical tools; numerical exercises aim at evaluating the skills in the use of statistical tools in a quantitative analysis to exhaustively summarize data and to study the relationships between two or more variables; open form questions mainly aim at evaluating the knowledge acquired on the methodological aspects of the program and students’ skills in discriminating among different statistical procedures. The short paper is based on the statistical software R and deals with real data analysis, specification and estimation of a regression model and the critical evaluation of the obtained results. The oral exam consists of some questions about the theoretical and methodological aspects of the program and allows to test students’ skills in explaining concepts with appropriate terminology. The final mark, expressed in thirtieths, is obtained as average score of the marks obtained in each partial evaluation. To pass the exam students must demonstrate to have acquired a basic knowledge of the topics and must get at least 18/30. To obtain the maximum grade students must demonstrate to have acquired an excellent knowledge on all the topics, language skills, ability to link the various topics and to apply the acquired knowledge to real problems.
Lesson mode
The theoretical lectures are conducted in a traditional way. Lectures devoted to empirical analysis of real data are conducted on the computer, using the R software.
